Sentence examples for laser surface hardening from inspiring English sources
In recent years laser surface hardening using pulsed laser sources has become an increasingly established technology in engineering industry and has opened up wider possibilities for the application of selective surface hardening.
Moreover in laser surface hardening this problem is even more important because melting of the target material should be avoided, surface roughness plays an important role and, sometimes, the surface is coated with absorbent layers.
The laser surface hardening has been carried out using uniform beam technology.
Laser surface hardening is a promising technology to improve wear and fatigue properties of steel surfaces.
In the present work, a C-Mn low carbon automotive steel sheet has been used for laser surface hardening treatment.
Laser surface hardening is a well-established process for enhancing the mechanical properties of selected surface areas of engineering parts made of different types of steel.
The microstructure of the laser surface hardened zone consists of ultrafine mixed carbides (M23C6, M7C3, MC or M2C) dispersed between martensite laths.
The present study reports the effect of laser parameters on the microstructure, and consequently, the wear resistance of laser surface engineered (hardening and melting) AISI H13 tool steel (in hardened and tempered condition) substrate.
The results show great advantages of laser beam surface hardening because only low distortion occurs and the properties of the steel substrates are improved without losing good coating properties.
The steel sheet has been successfully surface hardened using high power diode laser up to certain depth (250 300 µm) to make layered composite structure through its thickness.
