Ubuhlobo phakathi ukuqina kokungeniswa ubulukhuni nokumelana nokugqoka

Ukumelana nokugqoka akuhlobene kuphela nezinto ezibonakalayo, kodwa futhi nendlela yokugqoka. Izinhlobo zokugqoka ezijwayelekile zifaka ukuguguleka, ukunamathela okunamathelayo, ukugqokwa kwe-oxidative, nokugqokwa kokukhathala.

1. Ukukhathala kokugqoka, ukugqoka kokukhathala kuncike kwikhwalithi ye-metallurgical, njenge-porosity, ama-pores, amabala amhlophe, ama-non-metallic inclusions, njll, futhi akuhlangene nobulukhuni. Ukuthuthukisa ikhwalithi ye-metallurgical kungathuthukisa ukumelana nokukhathala kwensimbi.

2. Ngaphansi kwesimo sokugqoka kwe-abrasive, izici eziyinhloko ezithinta ukumelana nokugqoka ziwubulukhuni nokuhleleka. Uma umthwalo womthelela umncane, ukumelana nokugqoka kuhambisana nobunzima, okungukuthi, ubunzima bungasetshenziswa ukukala ukumelana nokugqoka. Uma umthwalo womthelela mkhulu, ukumelana nokugqoka kuphinde kuthinteke amandla nokuqina. Ngalesi sikhathi, i-surface Ubunzima abuyona ephakeme kangcono, kodwa kukhona ububanzi obuqinile obufanele, futhi ukumelana nokugqoka kuncipha ngemva kokuba ubulukhuni budlule inani elithile. Imvelo, inani kanye nokusatshalaliswa kwama-carbides ensimbi kunomthelela omkhulu ekuphikisweni kokugqoka.

3. Ngokugqoka okunamathelayo, isimo sinzima kakhulu. Imvamisa, izinto ezi-brittle kanye nezindawo zokuncibilika eziphakeme zimelana nokugqokwa kokunamathela. Ukunciphisa i-friction coefficient kungathuthukisa ukumelana nokugqokwa. Izinto ezinokuqina okuphezulu zisiza ukunciphisa i-coefficient yokungqubuzana. Ukumelana nokugqoka kuhle, yingakho.

1. Ukuguga kwe-oxidative kuncike kakhulu ezingeni lokusabalalisa kwendawo yensimbi, izakhiwo zefilimu ye-oxide eyakhiwe, namandla okubopha kwefilimu ye-oxide ne-substrate. Kungakhathaliseki ubulukhuni. Ngakho-ke, kungabonakala ukuthi ubulukhuni buhlobene eduze nokugqoka ukumelana, kodwa akuyona yedwa.
