Abstracts
There are many kinds of surface treatments for automotive parts due to various objectives are required in
automotive industries, e.g. corrosion, wear- as well as fatigue resistance. Numerous automotive parts are
involved with mechanical loading. Consequently, the surface treatments providing wear and fatigue resistance
are usually mentioned. Carburizing, Nitriding and Carbonitriding processes are well-known methods for Thailand
industries and generally used to resist wear problems. For the fatigue resistance, mechanical surface
treatments, deep rolling and/or shot peening are applied to automotive parts. Compressive residual stresses
and work hardening layer at the surface and in near surface regions of the mechanically surface treated parts
are key to enhance the fatigue lifetime. However, a basic concept as well as details of the deep rolling and shot
peening are known unclearly in Thailand. Therefore, in this presentation, basic concepts and some details of
mentioned surface treatments will be addressed, especially deep rolling and shot peening processes that play
recently more and more important role for the automotive industrial chainin Thailand.
