Ceramic coating piston rod


Ceramic coaƟng is a surface treatment process that uƟlizes plasma spray technology to deposit a firmly adhered layer onto a prepared substrate. The ceramic or alloy feedstock is heated to a molten or semi-molten state and accelerated at high velocity onto the component. This results in a coaƟng with high surface finish and excellent adhesion, significantly enhancing the component's wear and corrosion resistance.
