Semhando yepasirese ine mukurumbira pasi rose sulfur calcined,graphitized carburizing agentuye kuderedza mumiririri wezvigadzirwa zvemakemikari, tinoedza kuumba kukosha kune anopfuura 3000 mahombe esimbi, nheyo uye zvidyarwa zvemakemikari munyika makumi matanhatu neshanu pasirese.

Chekutanga, zvigayo zvesimbi, mukunyunguduka kwesimbi uye zvigadzirwa zvesimbi, nekuda kwekunyunguduka kwenguva, kubata nguva, nguva yekupisa uye zvimwe zvinhu, kurasikirwa kwekunyunguduka kwekabhoni zvinhu musimbi yemvura kunowedzera, zvichikonzera kuti kabhoni yemukati musimbi yemvura haigone. kusvika pazvinotarisirwa kukosha kwekunatsa.Mukuita kwekunyungudika, chimwe chikamu checarburizer chinoiswa muchinangwa chikuru ndechekuwedzera kabhoni yemukati musimbi yakanyungudutswa, kuitira kunyungudutsa iyo yakakodzera simbi.

Vaviri, indasitiri yekukanda, carburizing agent inoshandiswa mukukanda, inogona kuwedzera zvakanyanya huwandu hwesimbi yakaraswa, kuderedza huwandu hwesimbi yenguruve, uye carburizing agent ine chinangwa chekuzora, inogona kunyatso kuvandudza hupenyu hwebasa rekukanda, kuvandudza zvishoma nezvishoma mhando.

Mumunda weinjiniya yemakemikari, iwo emuviri uye emakemikari zvimiro zvekudzikisa maajenti anodiwa kuve akajeka.Kabhoni sechinhu chinoderedza chinotora chikamu mukuita.Pasi pemamiriro ekupisa kwekushisa kwakanyanya, iyo kemikari chisungo che oxide chinotyoka, uye kabhoni sechinhu chinoderedza inoiswa oxidized, uye valence inowedzera.

Zvina, zvimwe zvimwe zvinhu zvakawedzerwa zvinobatsirawo kune carburizing agent, senge brake pad ine additives, senge friction zvinhu.
