Studies on Abrasion Resistant Materials Against Sand and Slime in a Rapid Current of Water and their Hardface-Welding (Report 3)

Abstract

In the previous report 1 and 2, results of abrasion testing by Quartz sand in a current of water, using shooting type testing apparatus, against fixed specimens. In this report, results of tests using rotating type testing apparatus are described. The metals to be tested are simple stirring fingers, driven around in a pot with quartz sand and water.
From the results of experiments, relation of hardness and abrasion resistance No. of various metals are reported. Resistance No. of Carbon steels and low alloy steels increase almost in proportion to their hardness.
But High Mn steel and High speed steel show good abrasion resistance, however brass does not show good abrasion resistance, for their hardness.
And other abrasion phenomena are also described together.
