What is Hardfacing?
Hardfacing
is a process of making the metal even more tough and hard by applying another
strong material on its surface. Materials like tungsten carbide work
wonderfully in industrial processes that go through extreme conditions like the
oil industry. Tungsten carbidehardfacing is hence a highly popular technique offering high levels of wear
and abrasion resistance at the required locations.
Uses of tungsten carbide Hardfacing
When tungsten carbide was first considered for hardfacing, the crushed granules that were irregular in shape did not offer the much-needed resistance. Due to their irregular shapes, the granules easily succumbed to extreme conditions of temperature and pressure in various industrial processes. The same gave rise to the invention of the modern process of creating perfectly shaped tungsten carbide grit using its powder along with an organic binder. The grit formed comes with high strength and resistance making it a perfect hardfacing material for the industry.
Tungsten carbide hardfacing in industry are used in applications like hardbanding, drill pipes, drill collars, etc. Tungsten carbide offers protection to the surfaces which is a necessity considering the extreme conditions in the industries. In addition to its applications, tungsten carbide hardfacing process is often used to restore some worn down surfaces of old parts of various machines and equipment in the industries.
It is more cost efficient hardfacing materials, the tungsten carbide ball grain has more impact and wear resistance mixture of WC and spherules with different composition and particle size having very high resistance to abrasion and impact. Non recurring welding with high hardness. Famous corrosion resistance, high cobalt alloy spheres with small friction coefficient can be used to solve the casing wear problem in an affordable way. Tungsten carbide is widely used in surfacing, deposited in a variety of tools and parts surface to form hard layer grinding , with its excellent characteristic it can improve the surface hardness , wear resistance, corrosion resistance significantly , and extend lifespan. In the longer run, it brings good economic effectiveness used in the oil industry and will widely spread to greater benefit.
