Kedu ihe dị iche n'etiti cemented carbide na tungsten steel?

Ruo ogologo oge, ọtụtụ ndị nọ na ụlọ ọrụ ahụ kwenyere na carbide cimented bụ tungsten ígwè.N'ezie, enwere ụfọdụ ọdịiche dị n'etiti abụọ ahụ.Ka anyị leba anya n'ihe dị iche n'etiti carbide cimented na nchara tungsten.

Carbide cimented bụ nke siri ike onyinye nke refractory metal na bonding metal site uzuzu metallurgy usoro, nke bụ alloy ihe na oke elu ekweghị ekwe.Ọ nwere njiri mara nke ịdị elu siri ike, ike dị elu, ịdị mma siri ike, nkwụsi ike na-eyi nke ọma na nguzogide okpomọkụ, ọkachasị ike ya dị elu na nguzogide dị oke mma, nke mere na ọ na-anọgide na-agbanwe agbanwe ọbụlagodi na okpomọkụ nke 500 ° C, ọ ka nwere ike ịdị elu. ike na 1000 Celsius C, ma nwee ụfọdụ njirimara nke seramiki ígwè.Enwere ike kewaa carbide cimented a na-ejikarị ụzọ atọ dị ka ihe mejupụtara ya na njirimara arụmọrụ ha si dị: tungsten-cobalt, tungsten-titanium-cobalt, tungsten-titanium-tantalum (niobium), na ndị a na-ejikarị eme ihe bụ tungsten-cobalt na tungsten. -titanium-cobalt Ogo alloy.

Tungsten ígwè, nke a makwaara dị ka tungsten-titanium alloy, ígwè dị elu ma ọ bụ ngwá ọrụ ígwè.Isi ike ya bụ Vickers 10K, nke abụọ na diamond, ma na-ezo aka na ihe mgbagwoju anya nke nwere opekata mpe otu carbide metal.Uru nke nchara tungsten dị na ike ya dị elu yana nguzogide iyi kacha mma.Ọ ka nwere ike inwe nnukwu ike ọbụna na 1000 Celsius, ya mere a na-akpọkarị ya diamond nke abụọ.Ogo ọka nke akụrụngwa carbide na-abụkarị n'etiti 0.2-10 microns.

Tungsten ígwè bụ nke simenti carbide, ma simenti carbide bụchaghị tungsten ígwè.

N'ikwu okwu n'ozuzu, a na-agbaze nchara tungsten site n'ịgbakwụnye tungsten akụrụngwa n'ime nchara a wụrụ awụ site na usoro nchara, ọdịnaya tungsten ya na-abụkarị 15-25%;mgbe cemented carbide bụ usoro ntụ ntụ na tungsten carbide dị ka isi ahụ na cobalt ma ọ bụ ndị ọzọ The bonding metal na-ejikọta ọnụ, na tungsten ọdịnaya bụ n'ozuzu karịa 80%
N'ikwu ya n'ụzọ dị mfe, ihe niile alloys nwere ike karịrị HRC65 nwere ike ịkpọ cemented carbide, yabụ tungsten steel bụ nke carbide cemented, mana n'ikwu ya n'ụzọ siri ike, carbide cimented abụghị nchara tungsten.
