Xa isinyithi sikhazimla, yipolycrystal eyenziwe ngeenkozo ezininzi.Ubungakanani beenkozo bungabonakaliswa ngenani leenkozo kumthamo weyunithi.Okukhona liphezulu inani, kokukhona lincinci ubungakanani beenkozo.Inani leenkozo kwiyunithi yecandelo lomnqamlezo okanye umyinge wedayamitha yeenkozo zihlala zisetyenziselwa iinjongo zokulinganisa.Ubungakanani bengqolowa yentsimbi bunempembelelo ebalulekileyo kwiipropati ezininzi zetsimbi.Umphumo we-tungsten carbide ubungakanani beenkozo ngokuyimfuneko yimpembelelo yobukhulu bomda wengqolowa.Okona kucotha ubungakanani beenkozotungsten carbide, inkulu indawo yomda weenkozo kunye nefuthe elikhulu kwiipropati.Kwiqondo lobushushu begumbi kwiipropathi ezisebenza ngesinyithi, ubukhulu becala ukucotha kweenkozo, kokukhona ukomelela kunye nokuqina okuphezulu, ngelixa iplastiki kunye nokuqina kukwangcono.Oku kungenxa yokuba, okukhona inkozo icolekileyo, kokukhona ukuguqulwa kweplastiki kunokusasazeka kwiinkozo ezininzi, ukuze iplastiki ifane ngakumbi.
i-deformation, i-concentration encinci yoxinzelelo lwangaphakathi;kwaye okukhona kucotha iinkozo, kokukhona ujongano oluyikristale ngakumbi, kokukhona imida egobileyo yeenkozo;amathuba amaninzi okudibanisa okuziinkozo kunye neenkozo, ukuchasana ngakumbi ekusasazeni nasekuphuhliseni iintanda, ukuqina komnye nomnye, ngcono amandla kunye nokuqina.Itheyibhile idwelisa isiphumo sobungakanani beenkozo kwiipropathi zomatshini zentsimbi ecocekileyo.Ukusuka etafileni kunokubonwa ukucokisa okuziinkozo ukuphucula iimpawu zentsimbi kwiqondo lobushushu begumbi kudlala indima enkulu, ke ngoko, kusoloko kunethemba lokubaiimveliso ze-tungsten carbideIsixhobo sokugqwesa ingqolowa ingcono.
Kodwa kumsebenzi wokushisa ophezulu wezinto zetsimbi, ingqolowa inkulu kakhulu okanye incinci ayilungile.Ke ngoko, ngokuqhelekileyo ufuna ukufumana ubungakanani obuphakathi kweenkozo, kodwa kwezinye iimeko nethemba lokuba iinkozo zirhabaxa kwaye zinkulu ngcono.Umzekelo, ukwenziwa kweenjini zombane kunye neziguquli zifana nephepha lentsimbi yesilicon, ingqolowa irhabaxa, ilahleko yeteyiphu encinci, kokukhona iphezulu ukusebenza kakuhle.Ngamafutshane, impembelelo yobungakanani bengqolowa ekusebenzeni kwetsimbi ininzi, kuhlalutyo oluthile lwemeko ethile
