Writing reports of the project with inference of Scanning Electron Microscopy, X-Ray Diffraction, Atomic Force Microscopy, Optical Microscopy, Differential Scanning Calorimetry, Optical properties of metal surface and other data related to the individual project.
I would like to work in any closely related field. I have good theoretical knowledge in inorganic solid structure and engineering materials. My resume follows this letter. I possess excellent oral, written communication skills.
I would be grateful to you if you arrange an interview/meeting and give an opportunity to work in ShriRam institute. I am eagerly waiting for your reply.

CURRICULUM VITAE
OBJECTIVE  :
Seeking a quality environment, where my skills, experience and knowledge in Material Science/Electrochemistry/Metallurgy/Aerospace Surface Engineering can be shared and enriched. I am looking for an opportunity in Research and Development.

WORK EXPERIENCE  :
1. JOB PROFILE  :
Organization  : National Aerospace Laboratories. National Aerospace Laboratories is India’s premium R&D laboratory for aerospace and related field. It is one of the largest laboratories of CSIR (Council of Scientific and Industrial Research)
Department  : Surface Engineering Division
Designation  : Technical Assistant
Period  : 18.12.2001 to 30.04.2003 and 01.01.2008 to 31.12.2008.

Nature of Work :
#A  :
I used to conduct Electro gravimetric experiments by Pulse and DC methods. I used to conduct Tribology experiments by G 99 method. I know to Handle Equipments pertaining to characterization of samples. Preparation of samples for Micro hardness, Optical microscopy, X-ray Diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray, Atomic Force Microscopy, Emission of heat, reflection of light, Surface roughness, Differential Scanning Calorimetry. I prepared reports of the projects.

# B  :
Conducting gravimetric experiment (DC electroplating, Pulse electroplating and Electro less plating)  :
** Preparation of plating bath, Pretreatment of the substrate by cleaning with an organic solvent, weighing, mask no plating areas of the substrate dipping in the bath, cathode cleaning. Weigh the sample before and after the experiment.
** A characterization of the sample includes observations by naked eye, image analysis, surface hardness, cross sectional hardness. For cross section image and hardness, give copper backup, mount in Bakelite or acrylic cold cure, grind and polish for micro structural and micro hardness analysis of the sample, SEM and XRD analysis, EDX, check absorption and emission etc.
** Writing reports of the projects and present it to the project leader/Senior Scientist  : Bath composition, Substrate, thickness of deposition, Deposition time, temperature, pH, deposited weight (thickness), Micro hardness of cross section and surface hardness analysis in general plating, absorption, emission, EDX.
** For DC electroplating experiments Current density and anode.
** For Pulse plating experiments Current efficiency, Anode, Duty ratio, Average current density, peak Current Density and voltage. Electroplating Experiments Work report of the procedures and Methods

1 .Direct Current and Pulse plating of Cobalt  :
Bath Composition – Cobalt chloride (CoCl2), CoH4N2O6S2 (Cobalt sulphamate), H3BO3(Boric acid), SLS.
Anode-Platinum, Cathode-Brass, current density and duration were varied.
Experiments were carried out in DC and Pulse power supply. In pulse plating duty ratio, peak current density, and average current density were set. Pulse plating experiments were done using Pulse power supply instruments which had high end electronic system.
Grey smooth coating was obtained. No pits. Dendrites were formed at higher current densities. Samples were sent to XRD, hardness analysis.

2. Cobalt-Nickel co-deposition  :
Co-Ni alloy were deposited on Mild steel samples. The first experiment was done without Co content in the bath. And in the series of experiments, the concentration of Cobalt sulphamate was gradually increased till a smooth coating with stress free coating was obtained. Bath Composition  : NiCl2 (Nickel chloride), Ni (SO3 NH2)2 (Nickel sulphamate), SLS, CoH4N2O6S2 (Cobalt sulphamate) Substrate-Mild steel, Anode-Nickel, temperature-45C. The PH of 4.0 gave hydroxide coating, so PH was reduced to 2.5.

Grey smooth deposits were formed. A few samples had pits. The hardness of the coatings increased as the concentration of Cobalt sulphamate increased in the plating bath. The colour of the coating was darker with the increase of Cobalt sulphamate. A maximum hardness of 480 HV was obtained when the concentration of Cobalt sulphamate was 30ml/l. EDX report revealed 25 percent Co and 75 percent Ni. The samples were sent to XRD.

3. Solar Selective Coating  :
An alloy of Co-Ni-W was deposited on Mild steel substrate to find out absorptivity and emission of light radiation of the coatings. By convection water is heated in solar panels.

Bath Composition  :
NiCl2 (Nickel Chloride), NiSO4 (Nickel sulphate), Co H4N2O6S2 (Cobalt sulphamate), NaWO3 (Sodium tungstate).
Cathode- Mild steel, Anode- Platinum, temperature-70C, PH-1.0, duration-10 minutes, Current density- Below 50mA/in2.
The results were Alpha=0.8, Epsilon=1.0

4. Commercial Brightener for Electroplating  :
ALPHA MU+, with combination of APLHA 210+ and ALPHA 210B+ are commercial brighteners which were experimented on acid bath of Copper solution of 56g/l. The current density was varied. 200mA/inch2 gave good coating and brightness.
Bath composition  : CuSO4 (Copper sulphate), H2SO4 (Sulphuric acid), Brighteners Combinations of APLHA 210+ with ALPHA 210B+ and ALPHA MU+
Duration  : 1 hour, Anode- Copper, Cathode- Brass, no stirring, Room temperature.
Higher current densities gave streaks on the coating. The bright copper coatings got tarnished within a few days after the experiments.

5. Nickel-Phosphorous bright coating  :
Ni-P was coated on Brass samples for bright surface coatings. Bath Composition  : NiCl2 (Nickel Chloride), Ni(SO3 NH2)2 (Nickel Sulphamate), H3PO3(phosphoric acid), SLS.
Anode- Nickel, Cathode- Brass, Temperature- 60C, PH-4.0
Current density was varied, bright and thick deposit was obtained. Current efficiency was good. The surface hardness of the samples was recorded.

6. Bright and Hard Coatings  :
Ni-P coating with good brightness was obtained by adding saccharin.

Bath Composition  :
NiCl2(Nickel Chloride), Ni(SO3 NH2)2 (Nickel sulphamate), NaH2PO2(Sodium hypo Phosphate), Saccharine.
Anode- Nickel, Cathode- Brass, temperature- 60C, PH-1.5, Current density=200mA/inch2
The samples obtained had good brightness, but micro cracks were found in the coatings while taken for hardness.

#C  :
** Handling Pin on Disc Apparatus that is G99 method for tribology studies. Comparative study of different metals and alloys by Pin and disc is done. Find its wear and friction coefficient of sliding contact. Sliding occurs between a stationery pin and rotating disc which is fixed on a chuck by Allen screws. Normal load, rotational speed of the disc, wear track diameter, dry/ lubrication condition and time has to be varied. Tangential frictional force and wear are monitored by electronic sensors. The parameters available as a function of load, speed, lubrication, environmental condition for continuous monitoring. The data of the experiments are recorded by the system by software. The software generates reports of the results by analyzing the parameters (Wear, Friction and Time).
** Surface examination of the disc is done. The wear track and the kind of wear of the specimens is noted (abrasive wear, adhesive wear). The wear debris is collected and sent to SEM lab for EDAX.

#D :
Others  :
** Efficient at sample preparation techniques such as mounting, grinding with different grit size of emery sheets and polishing with Alumina slurry and diamond particle paste for metals and alloys. Remove Nickel coat of anodized aluminum substrate samples. Removing pits from Nickel-plated sunshield mirror panel of INSAT satellite series.
