Ts’ebetso ka mor’a ho thatafala ha nyeoe ea induction

1. Ho thatafala ka holim’a metsi: Ho thatafala ha holim’a lisebelisuoa tse tlas’a mocheso o phahameng le o bohareng oa maqhubu a ho futhumatsa holim’a metsi hangata ke li-unit tse 2 ho isa ho tse 3 (HRC) tse phahameng ho feta ho tima ho tloaelehileng.

2. Ho hanyetsa ho roala: Ho hanyetsa ho roala ha workpiece ka mor’a ho tima maqhubu a phahameng ho feta ho tima ho tloaelehileng. Sena se bakoa haholo ke liphello tse kopantsoeng tsa lijo-thollo tse ntle tsa martensite lera le thata, ho hasana ha carbide e phahameng, boima bo batlang bo le holimo, le khatello e phahameng ea khatello holim’a metsi.

3. Matla a mokhathala: ho tima maqhubu a phahameng le a mahareng ho ntlafatsa haholo matla a mokhathala le ho fokotsa kutloisiso ea notch. Bakeng sa li-workpieces tsa thepa e ts’oanang, botebo ba lera le thata le ka har’a moeli o itseng, ‘me matla a mokhathala a eketseha ka ho eketseha ha botebo ba lera le thata, empa ha botebo ba lera le thata le tebile haholo, lera le ka holimo. ke khatello ea kelello e hatellang, kahoo ho eketseha ha botebo ba lera le thata ho fokotsa matla a mokhathala le ho etsa workpiece. Brittleness ea eketseha. Kakaretso hardened lera botebo δ = (10 ~ 20)% D. loketseng haholoanyane, moo D. ke bophara bo sebetsang ba workpiece.
