Iringi yokuSila yeMill
Iinzuzo zobugcisa
Ukumelana nokunxiba kwezixhobo zokugaya kubalulekile. Ngokuqhelekileyo, abantu abaninzi bacinga ukuba imveliso inzima kakhulu, iya kunxiba ngakumbi, ngoko ke, ii-Foundries ezininzi zibhengeza ukuba i-castings yazo iqulethe i-chromium, isixa sifikelela kwi-30%, kwaye ubunzima be-HRC bufikelela kwi-63-65. Nangona kunjalo, okukhona ukusabalalisa ukusabalalisa, ubukhulu becala bokwenza i-micro-holes kunye ne-micro-cracks kwi-interface phakathi kwe-matrix kunye ne-carbides, kwaye amathuba okuphuka kuya kuba mkhulu. Kwaye okukhona inzima into, kokukhona iba nzima ukuyisika. Ngoko ke, ukwenza i-ring-resistant-resistant kunye nesigxina sokugaya akulula. Iringi yokugaya ikakhulu usebenzisa ezi ntlobo zimbini zilandelayo zemathiriyeli.
65Mn (65 manganese): esi sixhobo sinokuphucula kakhulu ukuqina kwendandatho yokugaya. Ineempawu zobunzima obuphezulu, ukuxhathisa okugqwesileyo kokunxiba kunye nokuxhathisa okuhle kwemagnetism, isetyenziswa ikakhulu kwintsimi yokulungisa umgubo apho imveliso ifuna ukususa intsimbi. Ukumelana nokunxiba kunye nokuqina kunokuphuculwa kakhulu ngokunyanzeliswa kwesiqhelo kunye nokufudumala ukushisa.
I-Mn13 (i-13 manganese): ukuqina kwe-ring ring casting kunye ne-Mn13 kuphuculwe xa kuthelekiswa ne-65Mn. I-castings yale mveliso iphathwa ngokuqina kwamanzi emva kokuthululelwa, i-castings inamandla aphezulu, ukuqina, iplastiki kunye neempawu ezingezonamagnetic emva kokuqina kwamanzi, okwenza indandatho yokugaya ihlale ixesha elide. Xa iphantsi kwempembelelo enzima kunye noxinzelelo olunamandla loxinzelelo ngexesha lokuqhuba, umphezulu uya kukwenza umsebenzi onzima kwaye wenze i-martensite, ngaloo ndlela yenze i-high-resistant surface layer, i-internal layer igcina ukuqina okugqwesileyo, nokuba inxitywe kwindawo encinci kakhulu, i-roller yokugaya ingakwazi ukumelana nomthwalo omkhulu wokuthuthumela.
