On the Abrasion Test of High Manganese Point : Wear of Deposited Weld High Manganese Metal

Abstract

To find out the prevention of defacement in case of deposited weld high manganese metal used for points of the railway, I have conducted experiments under the following conditions, i.e., lubricated and non-lubricated states and determinations made by using an Amsler type abrasion testing machine, employing slip velocities ranging from 0 to 15 cm/sec and contact pressures between 50 and 90 kg/mm². The test piece of tyre is about 0.7%C standard structure steel, and the other material of deposited weld high manganese metal. The results of tests indicated that : - 1) "Pitting" amount of the deposited weld high manganese metal is very little, and the effect of lubrication is very remarkable. 2) In case of austenitic structure, deposited weld high manganese metal, shows the same tendency of wear as cast high manganese steel.
