Hard alloy ndeye alloy zvinhu zvakagadzirwa kubva kune yakaoma komisheni yesimbi inomira uye yakasungwa simbi kuburikidza neupfu metallurgy process, nekuoma kwepamusoro, kusapfeka, simba rakanaka uye kuoma. Nekuda kwekuita kwayo kwakasiyana, inowanzoshandiswa kugadzira maturusi ekuchera matombo, maturusi emigodhi, maturusi ekuchera, maturusi ekuyeresa, zvichingodaro. Inoshandiswa zvakanyanya muminda yakadai seoiri uye gasi, indasitiri yemakemikari, mainjiniya einjiniya, uye kutonga kwemvura. Hard alloy chinhu chinogadzirwa nekutsikirira kuburikidza nehupfu metallurgy process.

1. Layered

Kuwanda kwakawanda kunotanga kubva kumicheto uye kunosvika mubillet. Chikonzero chekuiswa kweiyo compression block ndeye elastic yemukati kushushikana kana elastic tension mu compression block. Semuenzaniso, iyo cobalt yemukati yemusanganiswa yakadzikira, iyo carbide kuomarara kwakakwira, hupfu kana zvimedu zvakapfava, iyo yekugadzira mumiriri ishoma kana kugovaniswa zvisina kuenzana, musanganiswa wakanyanya kunyorova kana kuoma zvakanyanya, kudzvanya kwacho kwanyanya. hombe, huremu humwe hwakakura kwazvo, chimiro chechivharo chekutsikirira chakaoma, mold kutsvedzerera kwakashata, uye tafura yepamusoro haina kuenzana, izvo zvese zvinogona kukonzera layer.

2. Mitswe

Chiitiko chekutyoka kwenzvimbo kusingaite mubhuroko rakamanikidzwa kunonzi kutsemuka. Nekuda kwekusimba kwekushushikana mukati meiyo compression block yakakura kupfuura simba rekusimba reiyo compression block. Iyo tensile stress mukati meiyo compression block inobva kune elastic yemukati kushushikana. Izvo zvinhu zvinokanganisa delamination zvinokanganisawo makatsemuka. Matanho anotevera anogona kutorwa kuderedza kuitika kwekutsemuka: kuwedzera nguva yekubata kana kudzvanya kwakawanda, kuderedza kudzvanywa, huremu humwe, kuvandudza mold dhizaini uye zvakakodzera kuwedzera mold ukobvu, kukurumidza kukurumidza kudhirowa, kuwedzera kuumba vamiririri, uye kuwedzera zvinhu zvakasununguka density.
