Black Lake has offer a complete range of hard-facing to suit all drilling conditions. Through continuous improvement, we have leveraged on our experience and technical know-how to develop expertise on wear resistance and characteristics, as well as matrix hardness. Extensive in-house research has resulted in our best-in-class application process; the increased reliability in bonding is proven by track records on the field.
Users and manufacturers of drilling equipment seek to protect their tools with ultra-high-performance hard facing materials that are easy to use and ensure outs standing abrasion resistance under extreme conditions. Parts protected in this way are easy to repair
Crushed Tungsten Carbides are fused together within a tough polycrystalline matrix of nickel. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.
Geothermal Dressing: trapezoidal tungsten carbide inserts are held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage – ideal for high deviation drilling in abrasive formations.
Castolin: Cemented Tungsten Carbide inserts (TCI) embedded by powder spray deposit made of Nickel-Chrome based alloy, for very highly abrasive formations, recommended also for nonmagnetic steel body application
Castolin HF-5000 Manually applied WC-Wire rope process, medium to larger size tungsten carbide (WC) particles embedded in a nickel matrix. Type 5000 Hard facing is in a form of a Nickel core ﬂexible wire rope.
