Sezvatinoziva tese, kune akawanda marudzi ekutakura zvinhu mumusika, uye zvakajairika kutakura zvinhu zvinosanganisira mapoka matatu emidziyo yesimbi, porous simbi zvinhu uye zvisiri zvesimbi zvinhu.

Metallic zvinhu

Kutakura alloy, bhuronzi, aluminium base alloy, zinc base alloy uye zvichingodaro zvese zvinove simbi zvinhu.Pakati pavo, iyo inotakura alloy, inozivikanwawo sewhite alloy, inonyanya kuve alloy yemutobvu, tini, antimony kana mamwe masimbi.Inogona kuva nesimba rakaderera pasi pemamiriro emutoro unorema uye nekukurumidza.Chikonzero ndechekuti ine yakanaka kupfeka kuramba, yakakwira plastiki, yakanaka kumhanya mukuita, yakanaka yekupisa conductivity, yakanaka glue kuramba uye yakanaka adsorption nemafuta.Zvisinei, nokuda kwemutengo wayo wakakwirira, inofanira kudururirwa pagwenzi rinotakura rendarira, simbi yesimbi kana simbi yakakandwa kuti iite jira rakatetepa.

(1) Bearing alloy (inowanzozivikanwa seBabbitt alloy kana white alloy)
Bearing alloy ialloy yetin, lead, antimony uye mhangura.Zvinotora tini kana kutungamirira sematrix uye ine zviyo zvakaoma zveantimony tin (sb SN) uye copper tin (Cu SN).Mbeu yakaoma inoita basa rinopesana nekupfeka, nepo matrix akapfava anowedzera plastiki yezvinhu.Iyo elastic modulus uye elastic muganho wekubereka alloy yakaderera zvakanyanya.Pakati pezvinhu zvese zvinotakura, Embeddedness yayo uye friction kutevedzera ndizvo zvakanakisa.Zviri nyore kumhanya nejenari uye hazvisi nyore kuruma nejenari.Zvisinei, simba rekutakura alloy rakaderera zvikuru, uye gwenzi rinotakura harigoni kuitwa roga.Inogona chete kusungirirwa kune bhuronzi, simbi kana simbi yakaumbwa inotakura gwenzi seyakatakura lining.Kutakura alloy kwakakodzera mutoro unorema, wepakati uye wekumhanyisa nguva, uye mutengo unodhura.

(2) Copper alloy
Copper alloy ine simba rakawanda, antifriction yakanaka uye kupfeka kuramba.Bronze ine zvinhu zviri nani pane ndarira uye ndiyo inonyanya kushandiswa zvinhu.Bronze inosanganisira tin bronze, lead bronze uye aluminium bronze.Pakati pavo, tin bronze ine yakanyanya antifrict
