Abstract
ubi: metallurgy.
AGHA: ihe mepụtara metụtara ubi ntụ ntụ. Karịsịa ọ na-metụtara ịnata nke sintered hard alloy na ndabere tungsten carbide. Enwere ike iji ya maka imepụta ndị na-egbutu ihe, ihe na-akpụ ihe na onye na-egwe ọka. Alloy siri ike nwere 80.0-82.0 wt % tungsten carbide na 18.0-20.0 wt% nke njide. Njikọ nwere, wt %: molybdenum 48.0-50.0; niobium 1.0-2.0; rhenium 10.0-12.0; cobalt 36.0-41.0.
Mmetụta: ịnata alloy dị elu.
Nkọwa
Ihe nchoputa a metụtara ubi nke uzuzu metallurgy na maka mmepụta nke sintered siri ike alloys dabeere na tungsten carbide, nke a pụrụ iji maka mmepụta nke ndị na-egbutu ihe, ihe ọkpụkpụ, igwe igwe na ngwaọrụ ndị ọzọ.
Carbide siri ike ama ama nke dabere na tungsten carbide, nwere 3.0 ruo 20.0 wt.% Alloy binder nwere, wt.%: Cobalt 20.0-75.0; molybdenum - ruo 5.0; niobium - ruo 3.0 [1].
Ebumnobi nke mepụtara bụ ịbawanye ike nke alloy.
A na-enweta nsonaazụ teknuzu na n'ụdị alloy siri ike nke siri ike dabere na tungsten carbide nwere 80.0-82.0 wt.% Tungsten carbide na 18.0-20.0 wt.% Binder, ihe nkedo nwere, wt.%: Molybdenum 48 0-50.0; niobium 1.0-2.0, rhenium 10.0-12.0; cobalt 36.0-41.0.
Na tebụl. 1 na-egosi ihe mejupụtara nke alloy, yana ike kachasị na-ehulata. Na tebụl. 2 na-egosi nhazi nke ligament.
Tebụl 1 Ngwa mejupụtara, wt.%: otu 2 3 Wolfram carbide 80.0 81.0 82.0 Bunch 20,0 19.0 18.0 Mgbada Ike, MPa ~ 1950 ~ 1950 ~ 1950
Tebụl 2. Ngwa mejupụtara, wt.%: otu 2 3 Molybdenum 48.0 49.0 50,0 Niobium 1,0 1,5 2.0 Rhenium 10.0 11.0 12.0 Cobalt 41.0 38.5 36.0
A na-agwakọta ntụ ntụ nke ihe ndị na-emepụta alloy n'ụdị egosipụtara, a na-agbanye ngwakọta ahụ n'okpuru nrụgide nke 4.5-4.8 t / cm 2 ma tinye ya na ọkụ eletrik na okpomọkụ nke 1300-1330 Celsius C na oghere maka awa 7-9. N'oge sintering, ihe nkedo na-agbaze akụkụ nke tungsten carbide ma gbazee. Ihe si na ya pụta bụ ihe dị egwu nke usoro ya nwere tungsten carbide particles jikọtara ya na ihe nkedo.
