cemented carbidefor wear resistant shock resistant

Used alone or in combination with other wear resistant materials tungsten carbide whether in the form of cladding cast in steel or in the form of a weld overlay simply lasts where others fail It can offer wear life in excess of 5 times that of alumina ceramic and has ability for continuous operation a temperatures up to 900 degrees F (480 C) All of the following are highly wear resistant types of the ISO machining groups K10 – K50 Manufacturing of raw carbide – always profitable The starting materials for carbides are WC and Co powder which are mixed thoroughly with each other and kneaded into a plastic mass which can be extruded in rod form on extrusion presses

Fondag

RESISTANCE TO ABRASION AND MECHANICAL SHOCK: FONDAG is a concrete with low porosity and high density which is 7 to 10 times more resistant to wear than typical 5 000-psi portland cement concrete RAPID HARDENING: FONDAG generates high strength at an early stage with 24-hour compressive strengths of 8 000 psi to 9 000 psi (55MPa to 60 MPa)

Cemented Carbides used in end mills contain WC and Co only (i e two phases) and a few trace elements These grades are classified according to their cobalt content and WC grain size As shown in the diagram as grain size increases TRS values increase and wear resistance decreases

Wear resistance is the tool steel's ability to resist abrasive wear during cutting and forming Tool steels that have a high degree of both toughness and wear resistance are best-suited for cutting applications that require the tool steel to adsorb the shock of cutting punch entry as well as to withstand the abrasive rubbing that occurs during punch withdrawal (see Figure 2 )

May 01 2004Thermal Shock Resistance Thermal shock resistance is important to consider when choosing a cermet especially if interrupted cuts and coolant are aspects of the machining process Cermets tend to be more shock resistant than ceramics but less so than carbides

GC2145 has an even tougher substrate than gc2135 but still with very good resistance to thermal and mechanical shock The tough and wear resistant coating a PVd coating of TiAlN-TiN in combination with the very tough substrates makes gc2145 the perfect choice for cut-off to center and other applications with an extreme demand on toughness

The heat resistant properties of Fine Ceramics are measured by the temperatures at which they begin to melt and by their levels of thermal shock resistance Thermal shock resistance refers to a material's ability to withstand rapid changes in temperature Silicon nitride a particularly heat tolerant material displays superior resistance to
