Hardfacing with Metal Powders

Posted in The World Of Metal on 23rd June 2011

William Rowland are a leading supplier of Tungsten Carbide.

Hardfacing is a metalworking process where a harder metal material is welded to a base metal or another material. Hardfacing has two main purposes - to increase wear resistance and to restore worn surfaces.

By using this technique the results can often mean significant reductions in down-time of valuable equipment, as well as production costs. When using metal powders for hardfacing the process requires a layer of wear resistant material to be deposited over a base metal to prolong its service life. As always in these matters the end use application will determine how much longer the part would last by using this method, generally it is reported that the extended life should be at least three times longer than using the base metal on its own and can be up to 10 times longer in certain circumstances.

Depositing a layer of material like tungsten carbide, for example, imparts a hardness and wear resistance that cannot be matched by a base material such as carbon or stainless steel for instance. The end product is far cheaper than one that would have been produced by using the main metal or alloy, and thereby saves money. Tungsten carbide is only one brief example; there are many different metal powders suitable for an inexhaustible range of end uses.
Tungsten Carbide Suppliers

William Rowland are suppliers of Metal Powders, including Tungsten Carbide Powder

Market sectors that benefit from the use of metal powder coating / hardfacing technology include construction, excavation and the exploration industry, whereby mechanical shovel parts, digger teeth, buckets, drive sprockets and conveyor parts are usually produced in this method. In the mining sector this technique is frequently applied to dragline and a multitude of cutting tools and hydraulic equipment. The agricultural sector would find uses for metal coated parts in balers and root cutters, knives and harrow teeth for example.

The aerospace and automotive industry use proprietary, patented, nickel and other metal based alloys on parts like exhaust valves, camshafts, crankcases and a variety pump components.
