Plasma cladding coupled induction heating was developed and successfully used to fabricate Ni60A coating on the surface of copper pipe. By matching the swing arc with the rotating copper pipe, the cladding efficiency was as high as mm2/s. From the head to the tail of the coating, the wear resistance changed from to times that of pure copper. During the cladding process with

Iron ore is Australia''s largest source of export revenue, worth 117 billion (approximately US85 billion) in 2017. While the price of iron ore has been moderating some of the growth in export revenue in recent years, the volume of Australia''s iron ore exports is continuing to grow, albeit at lower rates.
