Аннотация

Neft va gaz qazib olishda, ayniqsa murakkab geologik sharoitlarda, samarali va ishonchli burg‘ilash juda muhim. Ushbu tadqiqotda tog‘ jinslarini burg‘ilash ishlarida qo‘llaniladigan volfram karbid-kobalt (WC-Co) asbob qistirmalarining to‘liq buzilish tahlili keltirilgan. Tekshiruv vizual tekshiruv, optik mikroskopiya, FESEM tasvirlash, EDS, WDXRF, XRD va mikroqattiqlik sinovlarini o‘z ichiga olgan. Natijalar shuni ko‘rsatadiki, abraziv yeyilish va materialning yopishishi asosiy buzilish mexanizmlari bo‘lib, yuqori kuchlanish va issiqlik ta’siri tufayli yeyilish asbobning chetlarida joylashgan. Elementlar tahlili yeyilgan yuzalarda Fe, Ca va Si kabi ko‘chirilgan materiallarni aniqladi, bu esa xizmat ko‘rsatish jarayonida asbob-tog‘ jinslarining o‘zaro ta’sirini ko‘rsatadi. WC qistirmalarining yuqori o‘rtacha qattiqligi 1350 Hv ni tashkil etdi, bu ularning qo‘llanilishiga mos keladi. Ajoyib ichki xususiyatlarga qaramay, tadqiqot shuni ko‘rsatadiki, xizmatdagi degradatsiya asbobning umrini cheklaydi. Tavsiyalarga abraziv burg‘ilash muhitida ish unumdorligini oshirish uchun mikrostruktura, mos moylash materiallari, bog‘lovchi moddalar tarkibi va sirt dizaynini optimallashtirish kiradi.
