Abstract

Investigation on friction coefficient under high pressure such as cold forging was carried out by pin-on-disk test. Pin specimens were made of chromium-molybdenum steel SCM415 as work material and disk specimens were made of four kinds of high speed tools steels and cemented carbide as die materials. Nominal stresses of 1000 to 167N/mm2 were loaded on the sliding surface of pin. The surface of the disk specimens was finished by #240, #800 emery papers or lapping. Friction coefficient of #800 polished disk showed lower value than that of mirror finished one. PVD treatments had good effect of low seizure properties. Especially, DLC treatment was free from seizure. The friction coefficient of P/M high speed tool steel H which contains appropriate dispersed carbide was lower than that of homogeneous microstructure AISI S7. This paper reports the friction coefficient relative to combination of materials, surface finish, surface treatment and load of specimens.
