Wisikhukhukazi esiqinileokothambisazengezwa ku-matrix yensimbi noma ye-ceramic njengezingxenye ze-element sintering exubile, izici ze-tribological zincike emvuleni nasekusabalaliseni kokusabalalisa kwezinto zokugcoba eziqinile ku-matrix ngesikhathi sokungqubuzana.
However, okokugcoba okuqinile kulahlekelwa ingxenye yokuthambisa kwawo ngenxa ye-oxidation kanye nokusha ngesikhathi sokucwiliswa kwezinga lokushisa eliphezulu.Ngesikhathi esifanayo, i-inhomogeneity yokusatshalaliswa kwe-lubricant eqinile kanye nokulimala kwayo ukuqhubeka kwe-matrix kuzonciphisa kakhulu amandla, ukuqina nokugqoka ukumelana kwezinhlanganisela.
Tindlela ekahle iwukuncibilikisa okokugcoba okuqinile okuncibilikisiwe ku-microporous ngokusebenzisa i-preform, ukwakha inhlanganisela yokungeniswa kwezinga lokushisa eliphakeme lokuzigcoba ngesakhiwo senethiwekhi ngesigaba se-matrix esiqinile kanye nesigaba sokuthambisa esithambile.
