Nchịkọta
UBI: ọrụ igwe.
IHE: ihe mepụtara a metụtara ntụ ntụ ígwè. Karịsịa, ọ metụtara ịnara ihe siri ike e ji sintered alloy dabere na tungsten carbide. Enwere ike iji ya mee ihe maka imepụta ihe e ji egbutu ihe, ihe e ji emegharị ihe na ihe e ji egwe ihe. Ihe e ji agwakọta ihe siri ike nwere 80.0-82.0 wt% nke tungsten carbide na 18.0-20.0 wt% nke njikọ. Ihe e ji agwakọta ihe 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 siri ike nke ukwuu.
Nkọwa
Ihe mepụtara a metụtara ọrụ nke igwe eji arụ ọrụ ntụ ntụ na imepụta ihe ndị e ji ígwè sintered sie ike dabere na tungsten carbide, nke enwere ike iji rụọ ọrụ nke ihe e ji egbutu ihe, ihe e ji akwọ ihe, igwe igwe na ngwaọrụ ndị ọzọ.
A maara carbide sintered nke dabere na tungsten carbide, nke nwere 3.0 ruo 20.0 wt.% Alloy nke nwere, wt.%: Cobalt 20.0-75.0; molybdenum – ruo 5.0; niobium – ruo 3.0 [1].
Ebumnuche nke ihe mepụtara a bụ ime ka ike nke ihe mejupụtara ya dịkwuo elu.
A na-enweta nsonaazụ teknụzụ n'ihi na n'ime ihe siri ike e ji sintered alloy dabere na tungsten carbide nke nwere 80.0-82.0 wt.% Tungsten carbide na 18.0-20.0 wt.% Binder, ihe njide ahụ 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 nhazi nke alloy ahụ, yana ike kachasị na mgbagọ. Na tebụl. 2 na-egosi nhazi nke ligament ahụ.
Tebụl 1 Ihe mejupụtara ihe mejupụtara ya, wt.%: otu 2 3 Wolfram carbide 80.0 81.0 82.0 Otu 20,0 19.0 18.0 Ike ịgbagọ, MPa ~ 1950 ~ 1950 ~ 1950
Tebụl 2. Ihe mejupụtara ihe mejupụtara ya, 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 mejupụtara alloy ahụ n'ọkwa egosiri, a na-etinye ngwakọta ahụ n'okpuru nrụgide nke 4.5-4.8 t / cm 2 ma gbanye ya n'ime ọkụ eletrik na okpomọkụ nke 1300-1330 ° C na vacuum ruo awa 7-9. N'oge sintering, ihe na-ejikọ ya na-agbaze akụkụ nke tungsten carbide ma gbazee. Ihe si na ya pụta bụ ihe dị oke arọ nke ihe owuwu ya bụ ihe tungsten carbide jikọtara ya na ihe na-ejikọ ya.
