ASTM F1978 is a test method used to evaluate the resistance of particle chipping of thermal spray coating. Chipping of thermal spray coatings is a problem with medical devices that assist motion in-vivo. Chipping particles within the body can result in serious health concerns and therefore must be addressed prior to human use. To determine the resistance to abrasion the metallic thermal spray is rubbed and rolled and particle shedding is observed.
