I-Tungsten carbide (i-hard alloy) inochungechunge lwezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle nokuqina, ukumelana nokushisa nokumelana nokugqwala, ikakhulukazi ubulukhuni bayo obuphezulu nokumelana nokugqoka, ngisho nasezingeni lokushisa elingu-500 ℃ empeleni ihlala ingashintshiwe. , futhi isenokuqina okuphezulu ku-1000 ℃.

I-Tungsten carbide, izakhi eziyinhloko yi-tungsten carbide ne-cobalt, eyenza u-99% wazo zonke izingxenye, 1% ezinye izinsimbi, ngakho-ke ibizwa ngokuthi i-tungsten steel, eyaziwa nangokuthi i-cemented carbide, futhi ibhekwa njengamazinyo embonini yesimanje. .

I-Tungsten carbide iyinhlanganisela yensimbi ehlanganisiwe eyakhiwe okungenani i-carbide eyodwa yensimbi.I-Tungsten carbide, i-cobalt carbide, i-niobium carbide, i-titanium carbide, ne-tantalum carbide yizingxenye ezivamile zensimbi ye-tungsten.Usayizi wokusanhlamvu wengxenye ye-carbide (noma isigaba) ngokuvamile uphakathi kwama-microns angu-0.2 no-10, futhi izinhlamvu ze-carbide zihlanganiswe ndawonye zisebenzisa i-binder yensimbi.Insimbi ebophayo ngokuvamile iyinsimbi yeqembu, futhi i-cobalt ne-nickel zivame ukusetshenziswa.Ngakho-ke, kukhona ama-alloys e-tungsten cobalt, ama-tungsten nickel alloys nama-tungsten titanium cobalt alloys.

I-Tungsten carbide sintering ukucindezela impushana ibe yinto engenalutho, bese uyishisisa esithandweni somlilo ukuze ube nezinga lokushisa elithile (ukushisa kwe-sintering), bese uyigcina isikhathi esithile (isikhathi sokubamba), bese uyipholisa, ukuze uthole. ukusebenza okufunayo kwempahla yensimbi ye-tungsten.
