We have extensive experience with HVOF (High Velocity Oxy-Fuel) Coatings. We will optimize your component’s performance by scientifically selecting the right coating for your application. We HVOF spray carbides and metal/alloys and utilize plasma systems to apply ceramic coatings.
Carbides are primarily used to create a hard surface to resist fretting, wear, erosion and to provide low coefficients of friction. Chrome carbides have an additional function of heat resistance and are generally prescribed for high temperature applications. These coatings are applied using high velocity equipment and generally will have the best bonding properties to the base materials. Common Carbides include: Tungsten carbide/stainless steel, Tungsten carbide/hastelloy, Tungsten carbide/nickel, Chrome carbide/nickel, Chrome carbide/nichrome and more.
Metals and Alloys are primarily used as bonding agents for ceramic multi-layered coatings; they are also used as dimensional restoration coatings. These types of coatings can be used in corrosive environments where their chemistry is applicable. Commom Metals/Alloys include: Inconel, Hastelloy, Monel, 17-4, 304, 316 stainless steel and others.
Accuraspray Plume Sensor System
We utilize the Accuraspray Plume Sensor System to provide real time evaluation of our thermal spray processes. This system allows process independent control of coating properties by providing real-time measurements of the average particulate temperature, velocity and flow rate as well as the vertical position and profile of the plume itself. Values of these parameters are continuously recorded and then compared to user adjustable tolerances. We know that the reproduction of coatings depends on the ability to monitor and control these key variables. This allows us to improve process control and better forecast coating thickness.
