BO’SHATISH (metallurgiyada) \u2014 toblangan po’latni 720\u00b0 dan (kritik nuqtadan) past temperaturagacha qizdirib, so’ngra asta-sekin sovitish. Bo’shatish beqaror martensitni barqaror holatga keltiradi, ichki kuchlanishlarni kamaytiradi va po’latning mexanik xossalarini o’zgartiradi, ya’ni ancha yumshatib, qovushoqligini oshiradi. Bo’shatishning 3 usuli bor; a) past temperaturada Bo’shatish \u2014 po’lat 200\u00b0 chamasi temperaturagacha qizdirilib, asta-sekin sovitiladi; b) o’rtacha temperaturada Bo’shatish \u2014 po’lat 200-450\u00b0 temperaturada qizdirilib, asta-sekin sovitiladi; v) yuqori temperaturada Bo’shatish \u2014 po’lat 450\u2014727\u00b0 temperaturada qizdirilib, asta-sekin sovitiladi. Bo’shatish temperaturasi oshgan sari po’latning qattiqligi va mustahkamligi pasayadi, plastikligi va zarbiy qovushoqligi oshadi. Bo’shatish usuli asbobsozlik po’latiga, tsementlanadigan po’latga, pishiq konstruktsion po’latga, prujinalar va ressorlarga, dinamik va titrama kuchlar ta’sirida bo’ladigan mashina detallariga termik (issiqlik) ishlovi berishda qo’llaniladi.<\/p>\n","protected":false},"excerpt":{"rendered":"
