8.
For all materials and tested conditions with in the investigation, the wear rate is increasing with the decrease with hardness values,
9.
For all materials wear rate increases with the increased load,
10.
The highest wear rate is observed in hardened AISI 52100 steel ball and the lowest wear rate is observed in vanadium carbide coated AISI 52100 steel ball,
11.
In all material combination, the dominant wear mechanism are adhesive and abrasive due to debris particles,
