  1. What is the hvof spray process and where is it used? HVOF stands for “High Velocity Oxygen Fuel”. The HVOF spray process is a thermal coating processthat is applied on metal surfaces of different equipment or parts of the machines. HVOF spray aims to develop a strong coating on the upper surface of the equipment. This effective and proven surface engineering process works wonders in extending the life of the equipment. The process is implemented by fluid forms of fuels with oxygen. In the machine, a combustion chamber is available where the mixture is poured and then ignited. It protects the equipment from external adverse conditions that can cause heavy wear and tear of the equipment. The process was first developed in the early 1980s as a subset of the thermal spraying process. You can now buy an HVOF spray toolkit which is very compacting, portable, and highly efficient from the best manufacturers in this domain.

  2. What are the advantages of HVOF spray? You can compare the HVOF spray process with other thermal spray processes to understand the differences. Undoubtedly, this is the most advanced surface coating process available to the manufacturing industries like automotive, aerospace, and heavy engineering. The most obvious advantages of this process are as follows: · The process offers a higher density of coating which means lesser porosity due to more intensive particle impact on the surface. · The process offers enhanced strength within the coating and a higher bond of the particles to the core substrate. · The higher velocity of injecting particles keeps the particles in the air for a lesser period than other types of thermal coating systems this means the coating possesses lesser quantities of oxidized particles. · The coated surface looks and feels smoother than other thermal spray processes due to high impact velocity and lesser porosity. · The coating shows a higher level of hardness that is naturally more sustainable than other types of thermal coatings. There are some disadvantages of this spraying process of which the manufacturers need to be aware before they use the process for surface coating. HVOF spray process coatings can be very intricate, with their properties and micro structure subject to numerous processing variables. Applications of the HVOF coating process This high-velocity spraying process is primarily used to develop high-quality coatings of “cermets” such as WC/Co or WC/Co/Cr. The thickness of the coatings is normally maintained within the range of 0.1-2.0 mm. The low level of porosity is another advantage of the system that remain within the range of 1- 2 vol%. The oxide content of the coatings remains within the range of 1-2.52t%. At the micro level, the bond strength remains within 80MPa. These unique characteristics help manufacturers in different industries to use the HVOF spray process in diverse engineering and manufacturing processes. These coatings can be applied in a cost-effective way for high-performing and long-lasting machinery parts and equipment. Endnote
