Study of Sliding Wear Behavior of Plasma Sprayed Red Mud Composite Coatings on Mild Steel 4

In this chapter a detailed explanation of the raw materials used for coating and the methods used to
study their characteristics is written. The coating procedure itself requires some basic preparation, i.e.,
shot blasting and cleaning. After plasma spraying, the coatings are subjected to series of tests like
XRD phase transformation, coating thickness, coating morphology, sliding wear test, wear
morphology, wear mechanism, co-efficient of friction, deposition efficiency, coating hardness, coating
porosity, thermal behaviour etc. The details are described below.
