A comprehensive scanning electron microscopy (SEM) analysis of the powders used in the drill bit's construction was conducted using the TESCAN Mira 3 LMU system. The analysis included tungsten carbide\u2013cobalt (WC\u2013Co) and diamond-containing composite powders. The results revealed that WC\u2013Co powders exhibit high density and uniform particle distribution, making them suitable for load-bearing components, while diamond-containing powders ensure superior cutting performance and wear resistance. Based on these findings, a rational material allocation was implemented: WC\u2013Co-based materials were used for structural elements, and diamond-containing powders were applied in cutting and undercutting inserts. Process was optimized to prevent thermal degradation of the polycrystalline diamond compact (PDC) inserts. The developed drill bit was designed for rotary drilling with an axial load range of 20\u201380 kN, rotation speeds of 80\u2013250 rpm, and a drilling fluid flow rate of up to 40 L\/s. The proposed design is particularly suited for the geological and technical conditions of Kazakhstan\u2019s oil and gas fields, contributing to reduced drilling costs and increased efficiency.<\/jats:p>","DOI":"10.4028\/p-hzo6um","type":"proceedings-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T08:12:43Z","timestamp":1767773563000},"page":"97-112","source":"Crossref","is-referenced-by-count":0,"title":["Enhancing the Wear Resistance of Drill Bits through the Improvement of Composite Diamond-Containing Elements"],"prefix":"10.4028","volume":"172","author":[{"given":"Volodymyr","family":"Khomenko","sequence":"first","affiliation":[{"name":"Dnipro University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akshyryn","family":"Zholbassarova","sequence":"additional","affiliation":[{"name":"Caspian University of Technology and Engineering named after Sh.
