Ukufa kwesihloko esibandayo sisitampu sokufa esifakwe kumatshini wokushicilela ukuze ubethe, ukugoba, ukuzolula, njl.
Intloko ebandayo yentloko iphantsi komthwalo onzima wokunyathela kwaye umphezulu wayo wokufa we-concave uphantsi koxinzelelo oluphezulu loxinzelelo.Izinto zokufa zifuneka ukuba zibe namandla aphezulu, ukuqina kunye nokumelana nokugqoka.Emva kokunyanga ubushushu, umphezulu wethutungsten carbide intloko ebandayo diekufuneka ibe nobunzima obuphezulu kwaye intliziyo kufuneka ibe nokuqina okulungileyo, ukuze umphezulu ube noxinzelelo oluthile olunokunciphisa uxinzelelo oluqhutywe kwinkqubo yesihloko esibandayo.Inokwenza ukufa kuhlale ixesha elide.
Ukonyusa ukusebenza kweemveliso zesihloko esibandayo se-tungsten carbide, zonke zethucarbide ebanda isihloko dieizikhenkce ziyacinywa kwaye zithotywe emva kwenkqubo ye-sintering.Inkqubo yokucima kunye nokufudumeza kukufudumala i-alloy blanks kwi-high pressure gas quenching furnace ukuya kwii-degrees ezingaphezu kwe-1300 kwaye ngokukhawuleza kwaye ngokukhawuleza zizipholise kwaye zifudumeze kwakhona ukuthoba.Kule nkqubo, njengoko iqondo lokushisa liphakama, i-solubility ye-tungsten carbide kwi-cobalt iyanda, kwaye iqondo lokushisa liphola ngokukhawuleza ukuze i-tungsten carbide echithwe kwisigaba se-cobalt ingabikho ngexesha, kwaye enye okanye yonke into igcinwe.Emva koko ucaphukile ukuphelisa ubulukhuni bangaphakathi obucimayo.Ngokulawula ukubola kunye nokusasazeka kwesisombululo esiqinileyo esigcweleyo, ukubunjwa kwe-metallurgical kunye nentlangano ye-alloy iyatshintshwa, kwaye ukusebenza kuphuculwe.
