Ubuhlobo phakathi ukunyanzeliswa ubunzima kunye nokumelana nokunxiba

Ukugqoka ukuchasana akuhambelani kuphela nezinto eziphathekayo, kodwa kunye nendlela yokugqoka. Iindlela eziqhelekileyo zokunxiba ziquka ukunxitywa kwe-abrasive, ukunxiba okuncamathelayo, ukunxitywa kwe-oxidative, kunye nokunxitywa kokudinwa.

1. Ukukhathala ukukhathala, ukukhathala kuxhomekeke kumgangatho we-metallurgical, njenge-porosity, pores, amabala amhlophe, i-non-metallic inclusions, njl., kwaye ayinanto yokwenza nobunzima. Ukuphucula umgangatho we-metallurgical kunokuphucula ukudinwa kwentsimbi.

2. Ngaphantsi kwemeko yokugqoka i-abrasive, izinto eziphambili ezichaphazela ukuchasana nokugqoka zilukhuni kunye nombutho. Xa umthwalo wempembelelo uncinci, ukunyanzeliswa kokugqoka kuhambelana nobunzima, oko kukuthi, ubunzima bunokusetyenziswa ukulinganisa ukuxhatshazwa kokugqoka. Xa umthwalo wempembelelo umkhulu, ukuxhatshazwa kokugqoka kuphinda kuchaphazeleke ngamandla kunye nokuqina. Ngeli xesha, umphezulu Ubunzima abukho phezulu bungcono, kodwa kukho uluhlu olufanelekileyo lobunzima, kwaye ukuxhatshazwa kokugqoka kunciphisa emva kokuba ubunzima budlula ixabiso elithile. Ubume, ubuninzi kunye nokusabalalisa kwee-carbides zetsimbi kunempembelelo enkulu ekuchaseni ukunxiba.

3. Ukugqoka i-adhesive, imeko inzima ngakumbi. Ngokubanzi, izixhobo ezibhityileyo kunye neendawo eziphezulu zokunyibilika ziyaxhathisa ukunxiba okuncamathelayo. Ukunciphisa i-coefficient ye-friction kunokuphucula ukuxhatshazwa kokugqoka. Izinto eziphathekayo ezinobunzima obuphezulu zinceda ukunciphisa i-coefficient ye-friction. Ukunxiba ukuxhathisa kulungile, naso isizathu.

1. Ukunxiba kwe-oxidative ikakhulu kuxhomekeke kwisantya sokusasazwa komphezulu wesinyithi, iipropathi zefilimu ye-oxide eyenziweyo, kunye namandla okubopha ifilimu ye-oxide kunye ne-substrate. Kungakhathaliseki ukuba lukhuni. Ngoko ke, kunokubonwa ukuba ubunzima buhambelana ngokusondeleyo nokugqoka ukuchasana, kodwa akuyena yedwa.
