Hvof Process
The hvof high velocity oxygen fuel thermal spray process is basically the same as the combustion powder spray process lvof except that this process has been developed to produce extremely high spray velocity.
Hvof process. The size of the powders used as feedstock materials is considered as critical factor for successful coating process. In hvof processes kinetic energy of particles is more important than temperature. A complete line of powders is available which is specifically engineered for application with the hvof system. The study of the hvof spraying process is useful for.
Like the other thermal spray techniques except cold spray hvof is not a solid state process since the coating materials are deposited on the surface of the substrate in a molten or semimolten state to tailor the desired coat. In classical developed between 1910 and 1920 but still widely used processes such as flame spraying and wire arc spraying the particle velocities are generally low 150 m s and raw materials must be molten to be deposited. There are a number of hvof guns which use different methods to achieve high velocity spraying. Developing new cost effective coating materials providing low porosity coating with better corrosion resistance indirectly controlling the damage and the risk of catastrophic failure due to corrosion.
We strive to meet outage turnaround and production schedules for less disruption to your business. High velocity oxygen fuel hvof coating is a thermal spray coating process used to improve or restore a component s surface properties or dimensions thus extending equipment life by significantly increasing erosion and wear resistance and corrosion protection. High velocity oxygen fuel hvof coating. Molten or semi molten materials are sprayed onto the surface by means of the high temperature high velocity gas stream producing a dense spray coating which can be ground to a very high.
The detonation gun d gun process was the first type of hvof process used. The powders should enjoy particle sizes in the range between 10 and 40 μm. Hvof process preventative predictive emergency hvof processes to protect your systems reladyne reliability services can help you achieve your goals through our comprehensive on site inspection plan and hvof processes. High velocity oxygen fuel hvof spraying is a group of thermal spraying processes which spray flames at supersonic speeds.
