| description | In recent years, surface modification using advanced heat source like laser has been
replacing the conventional methods to produce amorphous microstructure via rapid
solidification. Due to the benefits of laser to enhance the tribological and mechanical properties
of materials’ surface, several laser surface processing were developed including laser surface
modification, namely laser alloying, transformation hardening, surface amorphization, shock
hardening and glazing. In high temperature applications, the laser surface modification technique
is beneficial to prolong the die life cycle, and also to improve the surface roughness of thermal
barrier coatings (TBC). To produce the amorphous layer at a particular depth, laser parameter
such as irradiance, frequency, and exposure time are controlled. Variations of parameter may
result in modified microhardness properties of heat affected zone and transition zone.
Nevertheless, works on laser glazing of bearings, railroad rails and TBC had proven the surface
properties were enhanced through laser glazing to cope with excessive load, wear, fatigue,
bending and friction demand. |
