Nd-Yag (Neodymium Yttrium) pulsed wave laser has been used to modify and refine the surface microstructure of acicular bainitic ductile iron. The wear characteristics evaluated by adhesion and abrasion wear tests while friction characteristics evaluated by using strain gauge technique of the laser processed and unprocessed (as-cast) specimens were studied. The wear resistance and fric... https://www.hindigyanvishv.com/special-deal-Fluffy-White-Feather-Tinsel-Angel-Halo-quick-deal/
