The Effect of Plasma Spray Coating with Chromium Carbide on the Piston Surface

Emine Sap, Hanbey Hazar, Serhat Sap


In internal combustion engines, metal alloys are widely used. Wear, oxidation, fracture, and corrosion on the surface can be defined as deformations that can occur in metals. These deformations can have negative consequences for internal combustion engines. When these negative consequences are considered, metal alloy materials need to be healed. The process of depositing another material on the surfaces of the materials is called coating. to increase the strength of engine parts in difficult working environments, to prevent structural deterioration or to reduce the most, to provide strength in corrosive conditions, to prevent scratching and abrasion of mechanical friction. In this study, an internal combustion gasoline engine of a piston was plated with chromium carbide in a thickness of about 300 microns by plasma spray method. At the end of the coating process, plated over the piston and uncoated samples were taken. These samples were subjected to various experiments such as SEM, EDAX, X-RD, Microhardness, Mass Loss and Corrosion.

Keywords: Piston, Chrome Carbide, Plasma Spray Coating.
