Experimental Study of the Micro-Arc Oxide Coating Effect on Thermal Properties of an Aluminium Alloy Piston Head
The purpose of the present study is to investigate the influence of differently sized microarc oxidation coatings, applied
to the bottom of pistons made with an Al-12Si-Mg-Cu-Ni alloy, on its thermal properties by simulating the operation of a
real engine. This study is based on the premise that the alumina coating thickness affects the heat transfer and
temperature distribution in the piston. The analysis of thermal properties of pistons and suggestions for the optimal
thermal barrier coating thickness are presented
The Investigation of the Effect of Micro-Arc Oxidation Modes on the Adhesion Strength of Coatings
The paper presents the results of studies of the properties of hardened surface layers formed by micro-arc oxidation on
the workpiece surfaces of aluminum alloy Al-12Si-Mg-Cu-Ni. The authors attempted to determine the influence of
micro-arc oxidation modes on the properties of the modified layers. Investigation of the adhesion strength of the surface
layers formed at different concentrations of electrolyte components and analysis of the change in coatings adhesion
characteristics after thermal cycling were presented
