The feasibility and parameters optimization of AA5183 aluminum cladding on AISI 1018 steel by electro spark microwelding (ESM) and the corrosion resistance of the clad plate were investigated. The optimum conditions were found as 15 A, 10%, 800 Hz and 2500 rpm for P, D, F and R factors, respectively. Confirmation test under optimum conditions showed that the model can be effectively used to pre...

Initiation of corrosion on reinforcing bars occurs when a critical chloride concentration is achieved. A universal value for the chloride concentration that causes depassivation has not been agreed upon for carbon steels due to a variety of experimental factors. The chloride threshold depends on the rebar material, rebar surface condition, testing environment, method of detection, definition of...

In the present investigation, H13 tool steel has been deposited on copper alloy substrate using both CO2 and diode laser. A detailed parametric analysis has been carried out in order to find out optimum processing zone for coating defect free H13 tool steel on copper alloy substrate. Followed by parametric optimization, the microstructure and microhardness of the deposited clads have been evalu...
