Expert has expertise in various zinc plating processes. He has specialised in fastener coating, to have modified surface characteristics. His expertise are in Chloride zinc, Alkaline zinc, with various chromating finishes are very useful. He has very good exposure to change the co-efficient of friction in fastener coating application.
He has also helped the fastener industry, in identifying the Hydrogen embrittlement failures, and eliminating the effects of hydrogen embrittlement effect by improving the cathode efficiency and by introducing the baking process to de-embrittle the fasteners. He has also developed the test methods and fixtures to check the fastener hydrogen embrittlement effect.
Expert is also an expert in DIP Spin coating process like Dacromet, Geomet, Magni, PTFE coatings and Electroless process like Autophoretic and mechanical plating process.
He took a consulting project for Jai parabolic springs on specific model parabolic leaf spring, which has failed in less than 5000 cycles on fatigue loading. The entire process of manufacturing the spring including the stress shot peening process parameters has been established to have a fatigue life of more than 100, 000 cycles. The product was accepted by one of the major auto OEM.He had took a consulting project with Sterling tools Limited to established the zinc plating process and zinc phosphating process. The existing seven tank process has been reestablished to double the production without any capital investment. Another project taken by him in Sterling tools limited on Rust complaint from overseas customer has been resolved within no time. after going through the application of rust preventive oil on phosphated fasteners. The methodology of the oil application was changed to solve the problem.
