عملکرد muti aisi 420 پشتیبانی سفارشی
Nitrogen ions at various energy and dose have been implanted into the surface of AISI 420 martensitic stainless steel. • Nanohardness was improved by a factor of 2.3 when the implant energy and dose were 50 keV and 5 × 10 16 cm − 2. 5 × 10 17 cm − 2 should be the suitable dose for the improvement of wear resistance.
