Indandatho Yokugaya Yesigayo

Ukumelana nokuguguleka kwezesekeli zomshini wokugaya kubalulekile. Ngokuvamile, abantu abaningi bacabanga ukuthi uma umkhiqizo unzima, kulapho ugqoka khona kakhulu, ngakho-ke, izindawo eziningi zokusekela zimemezela ukuthi izinto zazo ezibunjiwe ziqukethe i-chromium, inani lifinyelela ku-30%, kanti ubulukhuni be-HRC bufinyelela ku-63-65. Kodwa-ke, lapho ukusatshalaliswa kusabalala kakhulu, kulapho amathuba okwenza imigodi emincane kanye nemifantu emincane ekuxhumaneni phakathi kwe-matrix nama-carbide akhula khona, futhi amathuba okuphuka nawo azoba makhulu. Futhi lapho into inzima, kulapho kuba nzima ukuyisika. Ngakho-ke, ukwenza indandatho yokugaya engagugi futhi ehlala isikhathi eside akulula. Indandatho yokugaya ikakhulukazi isebenzisa izinhlobo ezimbili zezinto ezilandelayo.

I-65Mn (65 manganese): le nto ingathuthukisa kakhulu ukuqina kwendandatho yokugaya. Inezici zobulukhuni obuphezulu, ukumelana nokuguguleka okuhle kanye nokumelana okuhle kwemagnetism, isetshenziswa kakhulu ensimini yokucubungula impuphu lapho umkhiqizo udinga ukususa insimbi. Ukumelana nokuguguleka kanye nokuqina kungathuthukiswa kakhulu ngokuvuselela nokulungisa ukwelashwa kokushisa.

I-Mn13 (13 manganese): ukuqina kokuphonswa kwendandatho yokugaya nge-Mn13 kuthuthukisiwe uma kuqhathaniswa ne-65Mn. Ukuphonswa kwalo mkhiqizo kuphathwa ngokuqina kwamanzi ngemva kokuthululwa, ukuphonswa kunamandla aphezulu okuthamba, ubulukhuni, i-plasticity kanye nezakhiwo ezingezona ezikagesi ngemva kokuqina kwamanzi, okwenza indandatho yokugaya iqine kakhudlwana. Uma ibhekene nokuthinteka okukhulu kanye nokuguquguquka kwengcindezi enamandla ngesikhathi sokusebenza, ubuso buzoqina umsebenzi futhi bakhe i-martensite, ngaleyo ndlela bakhe ungqimba olungaphezulu olumelana nokuguguleka kakhulu, ungqimba olungaphakathi lugcina ukuqina okuhle kakhulu, noma ngabe lugqokwe endaweni encane kakhulu, i-grinding roller isengakwazi ukumelana nemithwalo emikhulu yokushaqeka.
