Tungsten carbide bụ ngwakọta kemịkalụ inorganic nke nwere ọnụọgụ tungsten na carbon carbon. Tungsten carbide, nke a makwaara dị ka "carbide cimented", "hard alloy" ma ọ bụ "hardmetal", bụ ụdị metallurgic ihe nke nwere tungsten carbide ntụ ntụ (usoro kemịkalụ: WC) na ihe nkedo ndị ọzọ (cobalt, nickel. wdg).

Tungsten carbide bearing ohia na-egosi ike siri ike na ike mgbawa transverse, yana ọ nwere arụmọrụ dị elu na iguzogide abrasion na corrosion, nke na-eme ka a na-ejikarị ya n'ọtụtụ ụlọ ọrụ.

A ga-eji tungsten carbide bearing bush sleeve tumadi maka nkwado ntụgharị, nhazi, mgbochi mkpali na akara nke axle nke moto, centrifuge, onye nchekwa na onye na-ekewapụta mgbapụta ọkụ eletrik n'ime ọnọdụ ọrụ ọjọọ nke oke ọsọ na-agbagharị, ájá lash abrasion na gas corrosion na mpaghara mmanụ, dị ka slide bearx moto na ubi mmanụ. aka uwe.

Aka aka cemented carbide na-anabata akụrụngwa na ihe enyemaka dị ka tungsten carbide zuru oke, ntụ ntụ dị oke mma nke ọma, ngwakọta carbon nke ọma, igwe igwe bọọlụ, igwe na-akpali akpali, ihicha nkenke, ịpị nhịahụ dijitalụ na nrụgide sintering ahaziri post-processing na usoro ntụ ntụ ndị ọzọ. A na-eji akwa mkpuchi alloy siri ike mee ihe na ụlọ ọrụ mgbapụta pụrụ iche, yana ogologo ndụ ọrụ yana àgwà a pụrụ ịdabere na ya.

Uwe mkpuchi ohia na-arụ ọrụ na gburugburu abrasive n'ihi ntụgharị, esemokwu, wdg na ihe ndị na-etinye aka na mgbasa ozi.

Tungsten carbide bushing sleeve nwere eyi na nguzogide corrosion yana ike mgbaji dị elu maka ịchọ mkpali axial, ma nwee ike iru ihe achọrọ oke ohia ọdachi API.
