Ka 1923, scherter ea Jeremane e ekelitse 10% ho 20% Cobalt to Hung Polh, ebe o qapile lijo tsa carbide le cobalt. Ho thata ke la bobeli ho daemane feela. E entsoe ka koloi ea pele e halikiloeng. Ha u seha tšepe e entsoeng ka sesebelisoa sena sa sello sena, e tla tsofala kapele, esita le bohale bo khaotsoeng ba tla kotula. Ka 1929, Schwarzkov naheng ea United States e ile ea kenyelletsa palo e itseng ea carbide e itseng le titanoum carbide carbides ho mofuta oa sesebelisoa sa pele, se ntlafalitsoeng ts'ebetso ea sesebelisoa sa ho seha tšepe.

Hamorao, koae e halikiloeng e halikiloeng e ile ea hlaha. Ka 1969, Sweden e ile ea atleha ho ntlafatsa sesebelisoa sa kobo ea titanoum carbide. Bobuti ba sesebelisoa ke leqhubu la tingsterten-titanium-cobalt carbide kapa tukten-cobangt carbide. The thickness of the titanium carbide coating on the surface is only a few microns, but compared with the same brand of alloy tools, The service life is extended by 3 times, and the cutting speed is increased by 25% to 50%. Ka bo-1970s, moloko oa bone oa lisebelisoa tse koaetsoeng ka setotsoana se ile sa hlaha ka ho rema lisebelisoa tse thata tsa mochini.
