Zvishandiso zvakavharwa zviri musimba rakanaka uye kuomarara kwecarbide kana simbi yekumhanya kwazvo (
Ceramics, dhaimondi uye cubic boron nitride superhard zvinhu zvakaita serezor blades zvinogona zvakare)
Pamusoro, uchishandisa nzira yekuisa mhute yekuputira dhizaini yekupfeka-inodzivirira refractory simbi kana nonmetal kombindi nekugadzirira.
Kupfekedza sechivharo chemakemikari chechivharo chekucheka uye chinopisa chinopisa, chinogona kuderedza kupararira uye kuita kwemakemikari pakati pecheki uye workpiece, nokudaro kuderedza matrix ekupfeka uye kubvarura, kuitira kuti uvandudze hupenyu hwebasa rekucheka maturusi.
Zvishandiso zvakashongedzwa zvine kuomarara kwepamusoro uye kupfeka kuramba, kugadzikana kwemakemikari zvivakwa, yakanaka kupisa kupisa kune oxidation, yakaderera friction coefficient uye yakaderera thermal conductivity, inogona kuderedza iyo adhesion phenomenon, hazvisi nyore kugadzira bundu re devolop nezvimwe, kana kucheka maturusi akavharidzirwa akakwira. kupfuura isina kuvharwa yekucheka chishandiso hupenyu uye kucheka nekukurumidza kunowedzera kutsetseka, zvakawanda zvinogona kuderedza kurasikirwa kwechigadzirwa chekucheka.
Zvishandiso zvakavharwa zvichakamurwa kuita marudzi mana: maturusi esimbi anomhanyisa, maturusi akavharidzirwa ekucheka maturusi, pamwe chete nekeramics uye zvinhu zvakaomarara (
Dhaimondi kana cubic boron nitride)
Iyo blade pamidziyo yakavharwa.
Asi pamberi pemhando mbiri dzematurusi akashongedzwa anonyanya kushandisa.
Mune ceramics uye super hard material coatings pablade kuomarara kwaive kwakadzikira pane izvo zvematrix zvinhu, chinangwa ndechekuvandudza kuomarara kwekutyoka kweblade surface (
Inogona kuwedzera kupfuura 10%)
, inogona kuderedza kumucheto kweblade uye kukuvadzwa, kuwedzera huwandu hwekushandisa.
