Premium-Quality HVOF Coating
JK 117 is a premium-quality tungsten carbide/cobalt powder for the deposition of high-quality HVOF coatings. Applied correctly using the Jet Kote HVOF system, JK 117 produces coatings with properties equivalent to Praxair D-Gun® LW-1N40 for use in industrial and aerospace applications. JK 117 coatings can be finished to <0.025μm (<1μ-inch) RA.
Typical Applications
JK 117 HVOF coatings are a suitable replacement for hard chrome plating and Praxair D-Gun LW-1N40 in many industries, e.g. in chemical and petrochemical plants on mechanical seal faces, gate valves, oil well drill bearings and pump casings, impellers, plungers and sleeves. They are also used on compressor shafts and feed screws. In the aerospace industry, JK 117 protects aircraft compressor blade interlocks and airframe components such as flap and slat tracks, landing gear, and actuators. It resists abrasion, low-angle erosion, sliding wear and fretting.
Customer Specifications
JK 117 powder or coating meets customer specifications MSRR9507/1, AMS 2447-7, BMS10-67 Type I, DMS 2049 Type 5, B50TF167 CL.A, F50TF71 CL.A and DMR 33.019.
Finishing of JK 117 HVOF Coatings
JK 117 coatings are typically finished to 8 – 16 μ-inches by wet grinding with diamond media. They can also be super finished to below 1 μ-inch (0.025μm) if required. Coolant must be flooded onto part and wheel during grinding. The coolant may not contain amines. Spraying and grinding/finishing parameters for JK 117 are available on request.
