NAS offer two variants of HVOF Pistol Control Consoles to operate either liquid fuel or gas fuel pistols.
The Metallisation Met-PCC(HVOF) system is the latest development to our range of HVOF systems.
The Met-PCC(HVOF) system applies all of the simple control / operator interface features of our previous HVOF and Plasma systems. The ‘–L’ version can be interfaced with our own MET-JET4L pistol and/or other non-Metallisation liquid fuel pistols. The ‘-G’ version can be interfaced to a range of non-Metallisation gas fuelled HVOF pistols.
The Met-PCC(HVOF) system has re-packaged the control elements and utilised the latest technology to optimise functionality and reliability. At the front end, the operator interface utilises an intuitive Graphical User Interface (GUI), including the option to integrate video images into the display. The interface runs on a familiar touchscreen Windows PC platform with Intel Dual Atom processor which is great for usability, integration and communication. Behind the scenes, the latest PLC runs the system with communication between devices via the reliable Ethernet protocol.
As you would expect from a system of this standard, the gases/fluids are all mass-flow controlled for optimum repeatability of coatings. All spray parameters can have real-time trending on the system.
The result is a truly unique, compact design, flexible, easy to operate HVOF system, backed up by Metallisation’s 90 year+ industry experience and support.

In simple terms, this refers to a thermal spray coating process that is used to restore or improve components’ surface dimensions or properties. This in turn extends the equipment’s life by increasing their resistance to wear and erosion, while providing corrosion protection.
The process involves applying a high-velocity gas stream and high temperature, to spray molten or semi-molten materials onto these equipment’s surfaces. The aim is to produce a high-density spray coating creating a ground for a high surface finish.
The coating forms a hard structure with outstanding adhesion and exceptional hardness, that provides substantial corrosion protection and wear resistance of your metallic materials, alloys, and ceramics. All you need is to utilize the HVOF coating technique.
We understand the processes and the needs relating to HVOF coating, and we have everything you might need ready for purchase. We are always a call away, and you will have all your needs met. Our services aim to satisfying our customers and always paint a broad smile on their faces. We do this through creating a customer-buyer friendly environment by giving you the most reasonable prices for quality products.
What are the BENEFITS of HVOF coating?
- Reduced costs – Simply explained by the fact that you will lessen the number of repairs, or the need to replace your equipment as often.
- Improved performance – With reduced wear and tear, your equipment’s performance will be enhanced.
- Improved electrical properties.
- Enables components to operate, in both high and low temperatures.
- Your components can operate within harsher chemical environments – The reason behind this is due to the HVOF coating creating exceptional hardness combined with outstanding resistance to beat corrosion.
- Improves efficiency.
- Finally, HVOF coating improves the mating components’ life. No wear, no corrosion.
HVOF Coating Process Details
A mixuture of liquid or gas fuel and oxygen is inserted into a combustion tank or HVOF Coating chamber, where it is ignited and combusts over and over. The outcome is that hot gases create a pressure of around 1 Mpa and push through a converge-diverge nozzle and then travels though a straight away segment. The fuels created can be in liquid or gaseous state (propane, methane, hydrogen, natural gas, acetylane etc.) The minimum project velocity at the end of the barrel (>1000 m/s) passes the speed of sound in most cases. A powder stock is inserted in the gas stream, which speeds up the powder into ranges of 800 m/s. The powder and gas stream is then directed toward the surface of the substrate to be coated. Parts of the powder partially melt in the stream, and deposits onto the substrate. The outcome is that the coating has high bond strength and low porosity.
