Abstract
Ushbu ishda konstruktsion po‘latlar sirtini nitrooksidlash orqali mustahkamlash texnologiyasi o‘rganildi. Tadqiqotlar natijasida dastlabki oksidlash, azotlash va bug‘li oksidlash asosida hosil qilingan oksinitrid qoplamalar yuqori fizik-mexanik va tribologik xossalarga ega ekanligi aniqlandi. Oksinitrid qatlamlarining mikrotverdligi 8,5–12,5 GPa ga yetishi, ishqalanish koeffitsienti esa 0,04–0,07 oralig‘ida bo‘lishi qayd etildi. Qoplamalarning yeyilishga chidamliligi 30 % gacha oshgani va xizmat muddati 2–5 martagacha uzaygani aniqlandi. Olingan natijalar nitrooksidlash texnologiyasining tog‘-metallurgiya, neft-gaz va mashinasozlik sanoatida qo‘llaniladigan detallar ishonchliligi va uzoq muddat xizmat qilishini ta’minlashda samarali usul ekanligini ko‘rsatdi
