Sliding wear behaviour of two SLS materials: LaserForm and DirectSteel has been
investigated using Fretting tests, Pin-on-disc tests and microfretting tests. Wear
test conditions were determined by calculating Hertzian pressure for various loading
conditions, and wear tests were performed under both plastic and elastic contact
conditions. Wear analysis was subsequently done to find out the wear resistance
of materials. The wear volumes are presented against applied loads and dissipated
energies. It has been found out that LaserForm is better than DirectSteel and there
is no clear relation between hardness and wear resistance of materials.Mechanical Engineerin
