1. Place the material evenly into the baking tray attached to the vacuum oven, insert the baking tray into the drying rack, and push it into the drying box. Oxide powder for thermal spray refers to a type of powder material that is used in thermal spray processes. Thermal spray is a coating technique where a material in powder form is heated and propelled onto a substrate, forming a coating.

2. Close the bleed valve and drain valve, close the box door, and lock the box door with the four locking devices on the box door. Be careful not to tighten the locking device when vacuuming begins, in case the drying is finished. The air oven door does not open.
3. Open the vacuum valve and pump the vacuum. According to the performance of the vacuum pump, the pressure gauge is drawn to the limit value of the vacuum pump.
4. After vacuuming, first close the vacuum valve. If the vacuum valve is not closed, please replace it, then turn off the vacuum pump power.
5, the drying cycle of the material of the Institute, observe at intervals, pressure gauges, thermometers, and changes in the tank to deal with. If the pressure gauge index drops, it means that the water molecules in the vacuum drying oven are heated to generate a large amount of vaporized gas, and the pumping operation can be performed.
6. After the drying is completed, first open the bleed valve and put in the air. When the vacuum gauge pointer drops to 0, open the oven door and take out the material.
Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.
Some common types of oxide powders used in thermal spray include:
1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.
2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.
3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.
4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.
These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
