Ocwaningweni nasekuthuthukisweni kwemikhiqizo ye-carbide enosimende, sivamise ukuthatha "ukugcina ezinye izici ze-carbide enosimende kanye nokuthuthukisa ukuqina kwayo ngangokunokwenzeka" njengomgomo wocwaningo, ukuze sithole ukusebenza okungcono.

Njengezinto zensimbi, ukuqina kwe-carbide enosimende kungavezwa ngokokuqina komthelela kanye nokuqina kokuphuka. Kunobudlelwano bomugqa phakathi kokuqina komthelela namandla aguqukayo e-carbide enosimende. Izici ezinquma amandla e-flexural we-alloy nazo zithinta kakhulu ukuqina komthelela we-alloy. Ukuqina komthelela we-alloy nakho kuthinteka ezinye izici.

Ukuqina komthelela yikhono lempahla ukumelana nokwehluleka ngaphansi kokulayisha komthelela. Ukukhubazeka kwangaphakathi kuma-alloys kunemiphumela efanayo emandleni e-flexural kanye nokuqina komthelela. Ngokuvamile, ama-alloys aqinile ayizinto eziphukayo, futhi umsebenzi wokuguquguquka okunwebekayo ulandisa ingxenye enkulu uma ungaphansi komthelela, ngakho amandla okuguquguquka engxubevange anethonya elibalulekile enanini lokuqina komthelela.

Ku-alloy equkethe u-10% Co, ngokukhuphuka kosayizi wokusanhlamvu we-WC, nakuba ukuqina kokuphuka kwengxubevange kukhula, amandla okuguquguquka ayehla kanye nenani lokuqina komthelela nalo liyehla, okubonisa ukuthi amandla okuguquguquka adlala indima eholayo ekuqina komthelela. .

Njengoba ubulukhuni be-carbide kasimende bukhula, ukuqina kokuphuka kuthanda ukuncipha. Kodwa phakathi kwebanga elithile, kubonisa ukuthi ezinye izici nazo zithinta ukuqina kokuphuka ngaphansi kobunzima obufanayo.

Ngokuhlaziya ubudlelwano phakathi kokuqina komthelela, ukuqina kokuphuka kanye nezinye izakhiwo zemishini kanye nemingcele yesakhiwo se-carbide enosimende ekhiqizwa ukwakheka okuhlukile, usayizi wezinhlayiyana ze-WC nezimo zenqubo ezihlukene, sifinyelela iziphetho ezilandelayo:

Kunezici eziningi ezithinta ukubaluleka kokuqina komthelela we-carbide enosimende, ikakhulukazi okuhlanganisa ukonakala kwesakhiwo, amandla nokuqina, njll. Ukukhubazeka kwesakhiwo kwama-alloys kunciphisa amandla okugobeka kanye nokuqina komthelela ngesikhathi esisodwa. Amandla e-flexural we-alloy anethonya elikhulu ekuqineni komthelela.Ukuqina komthelela namandla okuguquguquka kugcina ubudlelwano obuthile bomugqa. Kuphela ngaphansi kwesimo samandla afanayo aguquguqukayo, ama-alloys anokuqina okuhle kokuphuka abonisa ukuqina komthelela okungcono.

Ukuqina kokuphuka kwe-carbide enosimende kuhlobene kakhulu nobulukhuni. Njengoba ubulukhuni bengxubevange bukhula, ukuqina kokuphuka kwehla ngokuyisisekelo, kodwa kushintshashintsha phakathi kwebanga elithile. Uma ubulukhuni bufana, i-low-Co coarse-grained alloy inokuqina okungcono kokuphuka. Ama-alloys akhiwe ngendlela efanayo anokuqina okuphezulu kokuphuka kodwa amandla aphansi okugobeka kanye nokuqina komthelela kunama-alloys angakhiwe ngendlela efanayo.

Uma kuqhathaniswa nevelu yokuqina komthelela we-carbide enosimende, inani lokuqina kokuphuka linokubaluleka okusebenzayo okubaluleke kakhulu. Ihlanganiswe nezinkomba ezintathu zokusebenza kwemishini yokuqina kokuphuka, ubulukhuni namandla aguqukayo we-alloy, Ingabonakalisa kangcono ukusebenza kwengxubevange.
