Abstract
Abstract A new wear resistant powder with a much finer particle size (0.07 to 0.15mm) is developed for better price and better performance. The new powder uses a mixed compound of Boron (B), Silicon (Si) and Carbon (C) with much less Tungsten (W). The comparison trial run of digging blades, hard faced with both new hard facing powder and traditional course Tungsten Carbide particle, showed the blades with the new mixed compound powder last approximately two times longer than blades hard faced with traditional Tungsten Carbide particles. It also decreased the difficulty when ploughing. The advantages of the new fine mixed compound powder for wear resistant hard facing are: 1. Cheaper than traditional hard facing materials made of mostly Tungsten Carbide particles 2. Comparison trial run of digging blades showed the service life of the blades hard faced with the new material is approximately double the blades hard faced with traditional Tungsten Carbide particles. 3. The smoother hard faced surface with a lower coefficient of friction allows for easier ploughing Traditional hardfacing 1h 4.1 New hardfacing 41' New hard facing with 100-150 mesh fine wear resistant powder, smooth finish.

Full description of this invention
Hard facing, a technique which applies high temperatures to melt wear resistant materials onto the surface of metal parts to improve their abrasion resistance has been successfully used in the mining and farm industry for years.
Up to today, the most widely used wear resistant material for hard facing is coarse Tungsten Carbide particles with a size between 0.60 to 0.90mm.
However, in recent years, the price of tungsten has increased rapidly to levels that are very difficult for people to afford. Hard faced surfaces with coarse tungsten carbide are also very rough with a high coefficient of friction, which is inefficient for wear resistance.
A new wear resistant powder with a much finer particle size (0.07 to 0.15mm) for hard facing has been developed for better price and better performance. The new powder uses a mixed compound of Boron (B), Silicon (Si) and Carbon (C) with much less Tungsten (W). The smoother hard facing surface with a low coefficient of friction and fine powder, also improves the wear resistance of the hard facing.
A comparison trial run of digging blades, hard faced with the new hard facing powder and traditional course Tungsten Carbide particle was conducted. It showed that the blades with the new mixed compound powder lasted approximately two times longer than blades hard faced with traditional Tungsten Carbide particles. Additionally, ploughing is easier using blades with the new hard facing powder.
The chemical content of the mixed compound powder for wear resistant hard facing is shown below:
c% | B% | Si % | Co % | w% | Cr% | Fe % | Ni % | ||||||||

*The size of the particle is 0.07 to 0.15mm.
The advantages of the new fine mixed compound powder for wear resistant hard facing are:
1. Cheaper than traditional hard facing materials made of mostly Tungsten Carbide particles
2. Comparison trial run of digging blades showed the service life of the blades hard faced with the new material is approximately double the blades hard faced with traditional Tungsten Carbide particles.
