Wear characteristics of spheroidal graphite roll WC-8Co

Mar 28,2010 Electro spark deposition of WC TiC Co Ni cermet coatings#0183;Electro-spark deposition (ESD) was adopted for preparing high property coatings by depositing WC-8Co cemented carbide on an spheroidal graphite roll substrate.The microstructure and properties of the coating were investigated by X-ray diffraction (XRD),scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) and ball-disc configuration wear tester.Understanding the Influence of High Velocity Thermaland toughness of the WC-Co coatings justify its better abrasion resistance.The presence of Ni on the metal matrix increases the free corrosion potential of the coating to more noble region.However,the WC-Co coatings show a lower corrosion rate and hence a higher protective performance than the rest of the coatings.US20040140292A1 - Micro-welded gun barrel coatings A micro-welding process is used to apply erosion and wear resistant coatings to the internal diameter of gun barrels.The applied coatings are then treated by methods such as honing and/or rotary forging.The protective micro-welded coatings may comprise ceramic,cermet and/or refractory metal materials,and may be used with rifled or smooth gun barrels of various sizes.
