Tungsten Carbide Blades
Site na nhọrọ ọkwa kacha mma, a ga-amụba agụba submicron n'ogo tungsten carbide ka ọ bụrụ agụba na-enweghị nhịhịa dị n'ime ya na-ejikọta ya na carbide ochie. Ọ bụ ezie na ọ bụghị dị ka ihe na-awụ akpata oyi n'ahụ dị ka ígwè, carbide na-eguzogide oke ike, yana ike ya na Rc 75-80. Enwere ike ịtụ anya ndụ agụba ma ọ dịkarịa ala 50X nchara agụba ma ọ bụrụ na ewepụghị chipping na mgbaji.
Dị ka ọ dị n'ihe gbasara nchara nchara, ịhọrọ ọkwa kachasị mma nke tungsten carbide (WC) bụ usoro dị mgbagwoju anya gụnyere nhọrọ ndị mebiri emebi n'etiti nguzogide iyi na ike / ujo. A na-eme tungsten carbide cimented site n'intering (na oke okpomọkụ) ngwakọta tungsten carbide ntụ ntụ na powdered cobalt (Co), metal ductile nke na-eje ozi dị ka "ihe nkedo" maka akụkụ nke tungsten carbide siri ike. Okpomọkụ nke usoro ihe ọkụkụ anaghị agụnye mmeghachi omume nke ihe mejupụtara 2, kama ọ na-eme ka cobalt ruo ebe dị nso na mmiri mmiri wee dị ka matrix gluu na-ekpuchi maka akụkụ WC (nke okpomọkụ na-adịghị emetụta). Akụkụ abụọ, ya bụ oke nke Cobalt na WC na nha nha WC, na-achịkwa nnukwu ihe onwunwe nke mpempe "cimented tungsten carbide".
Ikowapụta oke urughuru WC na pasentị dị elu nke Cobalt ga-ewepụta akụkụ na-eguzogide oke ujo (na nnukwu mmetụta). Ka nha ọka WC dịkwuo mma (ya mere, ka akụkụ WC dị elu nke a ga-eji Cobalt kpuchie) yana obere Cobalt na-eji ya, akụkụ ahụ ga-esiwanye ike ma na-eguzogide ọgwụ. Iji nweta arụmọrụ kachasị mma site na carbide dị ka ihe agụba, ọ dị mkpa iji zere ọdịda ihu akaghi aka nke chipping ma ọ bụ nbiji kpatara, ebe n'otu oge na-ekwe nkwa nguzogide iyi kacha mma.
Dị ka ihe bara uru, mmepụta nke akụkụ dị nkọ nke ukwuu, nke nwere nnukwu akụkụ na-egosi na a ga-eji ezigbo carbide na-eme ihe na ngwa agụba (iji gbochie nnukwu nicks na akụkụ siri ike). Nyere ojiji nke carbide nke nwere nkezi ọka nke 1 micron ma ọ bụ obere, arụmọrụ carbide agụba; ya mere, % nke Cobalt na akụkụ geometry akọwapụtara na-emetụta nke ukwuu. A na-edozi ngwa ngwa nke gụnyere ibu ujo dị oke oke ma dị elu site na ịkọwapụta 12-15 pasent Cobalt na ihu geometry nwere akụkụ akụkụ gụnyere ihe dị ka 40º. Ngwa ndị gụnyere ibu dị mfe ma tinye ego na ndụ ogologo agụba bụ ezigbo ndị chọrọ maka carbide nke nwere 6-9 pasent cobalt ma nwee akụkụ ihu gụnyere n'ogo nke 30-35º.
