Coatings based on bonding sintered Tungsten Carbide Inserts

Our DrilTec STC 400 series are coatings based on bonding sintered Tungsten Carbide Inserts (TCI) onto a tool body, using powder welding technology. The most commonly used powders are Nickel-based. However, powders containing Tungsten Carbide (WC) can also be used for filling between the inserts. The process can be used to apply a wide range of insert sizes and shapes, one of the most commonly used sizes are 13 to 15mm with width of 5mm and thickness varying from 3 to 4mm.

Process description
The surface to be protected is mechanically cleaned and then pre-heated; a thin layer of powder is then applied. Using a SuperJet Eutalloy torch, the inserts to be bonded to the surface are pre-heated and a thin layer of powder is applied to one side. A brick pattern is laid out on the component to be protected; the spacing is typically 3mm, but this can be adjusted, according to specifications. Using the SuperJet C Torch and our C6 tip, the inserts are bonded to the surface and the gaps are flood-filled with a Nickel-based powder such as OTP 126, OTP 331LT or OTP 220NM (for non-magnetic applications).
