An Overview of the Hardness Differential Required for Abrasion
This paper presents an overview of the hardness differential required for abrasion. Empirically, the abrasive must be at least 1.2 times harder than the worn surface if it is to produce a scratch. Thi...

Erosionwear is a process that accompanies the facility for hydraulictransportation of solids. Since the pump is one of thevital parts of this facility, the working life of thepump is conditioned by the amount of wear. The workinglife can be realized only if the parameters chosen, forthe pump elements, slurry, and transport conditions, will provide economictransport with minimal wear. Testing is the most reliable methodfor acquiring valid data. The two issues that need tobe solved while planning the testing process are the choiceof valid similarity criteria (test-industrial facility) and data selection. Afterthe theoretical analyses, technically acceptable similarity criteria are obtained. Agroup of data needs to be defined through the experiment.
