Materials and Coatings

The test program for porous coatings is very well defined and includes static tensile strength, static shear strength, shear fatigue strength, bending fatigue strength, abrasion resistance, as well as requirements for porosity. This applies to HA coatings, sintered beads, plasma sprayed Ti, as well as new technology such as metal scaffolding and 3D printed porous structures.

In addition to coating tests, Knight Testing routinely performs material testing for lot validation, new equipment validation, as well as manufacturing process evaluation. Recent projects include an evaluation of peening operations on CoCr, the influence of various laser marking parameters on spinal rods, and an evaluation of the influence of hot isostatic pressing on the fatigue life of 3D printed material.
