Pores mgbe Sintering

Carbide cimented bụ ụdị onyinye nwere tungsten nhata na carbon, nke nwere ike dị nso na diamond. Carbide cimented nwere nnukwu ike na ike siri ike n'otu oge ahụ. A na-eme carbide cimented site na metallurgy ntụ ntụ, na sintering bụ usoro kachasị mkpa n'oge imepụta ngwaahịa carbide cimented. Ọ dị mfe ịkpata pores mgbe tungsten carbide sintering ma ọ bụrụ na ejighị ya nke ọma. N'isiokwu a, ị ga-enweta ụfọdụ ozi gbasara pores mgbe tungsten carbide sintering.

A na-agwakọta ntụ ntụ carbide tungsten na ntụ ntụ n'otu akụkụ. Mgbe ahụ, a na-eme ntụ ntụ ngwakọta ahụ ka ọ bụrụ kọmpat akwụkwọ ndụ akwụkwọ ndụ ka a na-egwe ọka mmiri n'ime igwe igwe igwe, ịgbasa ihicha, na compacting. A na-agbanye kọmpat tungsten carbide akwụkwọ ndụ akwụkwọ ndụ n'ime ọkụ ọkụ HIP.

Enwere ike kewaa usoro isi ihe n'ime nkeji anọ. Ha bụ mwepụ nke onye na-akpụzi ihe na ogbo a na-ebu ụzọ emezi, ogbo ịgba ọsọ siri ike, usoro ịgbanye mmiri mmiri, na ogbo sntering jụrụ oyi. N'oge sintering, okpomọkụ na-abawanye nwayọọ nwayọọ. Na ụlọ ọrụ mmepụta ihe, e nwere ụzọ abụọ a na-ahụkarị maka sintering. Otu bụ hydrogen sintering, bụ nke a na-achịkwa ihe mejupụtara akụkụ site na mmeghachi omume kinetics na hydrogen na ikuku ikuku. Na nke ọzọ bụ vacuum sintering, nke na-eji ebe na-ekpo ọkụ ma ọ bụ ebe dị ala. Nrụgide gas na-achịkwa ihe mejupụtara carbide cemented site na ibelata mmeghachi omume kinetics.

Naanị mgbe ndị ọrụ na-ejikwa nlezianya na-achịkwa ọkwa nke ọ bụla, ngwaahịa ikpeazụ tungsten carbide nwere ike nweta microstructure na ihe mejupụtara kemịkalụ chọrọ. Ụfọdụ pores nwere ike ịdị mgbe a gbasasịrị. Otu n'ime ihe ndị dị mkpa mere bụ banyere sintering okpomọkụ. Ọ bụrụ na okpomọkụ na-ebili ngwa ngwa, ma ọ bụ okpomọkụ na-ekpo ọkụ dị oke elu, uto na mmegharị ọka ga-abụ nke na-adịghị mma, na-akpata ọgbọ nke pores. Ihe ọzọ dị mkpa kpatara ya bụ onye na-emepụta ihe. A ga-ewepụrịrị ihe nkedo ahụ tupu ịgbanye ya. Ma ọ bụghị ya, onye na-emepụta ihe ga-agbanwe n'oge okpomọkụ na-arịwanye elu, nke ga-eme ka pores.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe.
