Isku dhufashada

Waxaa lagu soo saaray 38CrMoALA oo tayo sare leh ama 1.8550 wax been abuur ah, oo leh deminta iyo xanaaqa HV290-320, dusha duulimaadka ee lagu sameeyay alxanka balaasmaha nikkel, dhumucdiisuna ≥1.7mm, qallafsanaanta HV860-980, fasalka 2 qaab-dhismeedka biraha ama ka sarreeya.

Foosto

Foosto waxay ka samaysan tahay qalab tayo sare leh oo 38CrMoALA ah oo been abuur ah, ka dib markii la demiyo oo u dabcay HB290-320, nitriding leh habka foornada NITREX ka dib mashiinka dhamaystirka, qoto dheer ee nitriding waa 0.5-0.7 mm, qallafsanaanta waa HV860-980, oo leh darajada 2 qaab dhismeed metallographic ama ka sarreeya.

Foostada waxaa loo nashqadeeyay sidii "la go'i karo", 42CrMo foosto waa la demiyay oo u adkeyd HB290-320, oo lagu dhejiyay gacmo-gacmeedka HPT1 ee Jarmalka. Dhumucdiisuna waxay ka badan tahay 7 mm, qallafsanaantu waa HRC58-62, qolofka foostada waa la isticmaali karaa, iyo gacanta daawaha gudaha waa la bedeli karaa ka dib markii uu dhammaaday.
