Plasma Spray

PLASMA SPRAY P017

A method of putting a hard coating on a base material.

Plasma spray is not recommended for mechanical seal faces. If you must use a spray coating the “D GUN” method is superior because it creates a chemical rather than mechanical bond with the base material.

The problem with all coatings is that they have a different expansion rate than the base material. In high temperature applications this can cause heat checking and cracking of the coated face
