Abstract: A differential hardness is needed for a spherical indenter to avoid large deformations of it during an indentation process. Tabor proposes a criterion for this, where the ball hardness should be at least 2.5 times harder ...

Abstract: A very useful model for predicting abrasive wear is the linear wear law based on the Rabinowicz's equation. This equation assumes that the removed volume of the abraded material is inversely proportional to its hardness. ...

Abstract: Hydroerosive grinding is used as a finishing and inlet rounding operation of diesel nozzles to improve the engine performance. A mixture of hard particles suspended in a carrier fluid circulates through the injection holes ...
