Purpose: Mainly used in cemented carbide YL electrode welding petroleum, mining, coal mining, geology, construction and other industries in a number of serious wear or a combination of cutting of workpieces. Such as: Shoes, wear shoes, lifter, enlarger, drill pipe joints, hydraulic cutting blades, plough planers, coring, piling, spiral drill bit, etc.
Cemented carbide HRA90~HRA92
Matrix: HRC 30
Flowing temperature 910~935 oC
Multi-edge particles can be used in the formation of the workpiece surface. For serious wear, with 1/3 of fine particles, need a broad particle size distribution to increase density and decrease in clearance of surfacing. Mesh size from 6.35MM--325 mesh. Hardness 90.5 (8%)
Polygon in the workpiece surface alloy into distribution. This enables tighter particle inclusions and reduce the gap. Applied to extreme wear and tear.
Three sizes: 8-10-16 16 14-20 5mm 8mm
Particle shape is gravity cutting most important discovery. Those with sharp points and the sharp edge of particle coating is not good, so that there is a gap between the particles, reduced cutting edge and serious exposure. Gravity cutting alloy particles will have a very powerful cutting or grinding surface. Apply to play grinding, cutting, drilling, sawing, tools.
The development of fine grades of coating alloy finds a solution to the problem of hard brittle, no wear-resistant due to softness.
