The FORM 3040 applicator developed by Daiichi Kigaku Co., LTD. is one of the most common applicators used for thermal spray processes. This type of applicator uses a small gas-fired heating element to transfer heat to the wire or powder that is sprayed onto the substrate. The heat transfer rate of the heating element is controlled by a combination of air pressure, the pressure at which the powder is fed into the heating zone, and the heating rate of the wire or powder.

The FORM 3040 applies a very uniform coating of thermal spray materials to the substrate, resulting in a uniform and consistent heat transfer rate. When using this type of applicator, it is very important to keep the coating temperature uniform across the entire substrate. To achieve this, the temperature of the powder or wire is monitored by an infrared temperature sensor and the heat transfer rate is adjusted to maintain the desired temperature.

In order to control the heat transfer rate and ensure a consistent temperature across the substrate, air pressure is used to maintain a constant flow rate of air across the substrate. Air pressure is typically adjusted to ensure that the powder or wire being sprayed is heated to the desired temperature before it hits the substrate. This is done by adjusting the air pressure to match the pressure at which the powder or wire is fed into the heating zone.

Once the powder or wire is sprayed onto the substrate, the surface of the substrate is cooled to the desired temperature. This cooling effect is achieved by a combination of air pressure, the pressure at which the powder is fed into the heating zone, and the heating rate of the wire or powder.

The heat transfer rate of the heating element is typically monitored by an infrared temperature sensor and the air pressure is regulated to maintain the desired temperature. To ensure that the coating is evenly applied to the substrate, the air pressure is also adjusted to ensure a uniform heat transfer rate across the entire substrate.

FORM 3040 applicators are also equipped with a secondary heat source that is used to increase the temperature of the substrate after the coating has been applied. This secondary heat source helps to prevent warping and cracking due to cooling too quickly. It also helps to ensure that the coating maintains its adhesion and integrity over time.

The FORM 3040 is an effective and cost-efficient way to apply thermal spray materials to a variety of surfaces. By using the heat transfer rate and air pressure adjustments, the applicator can achieve a uniform temperature across the entire substrate and ensure that the coating is uniformly applied to the surface. In addition, the secondary heat source helps to prevent warping and cracking due to cooling too quickly, while also helping to maintain the integrity of the coating over time.
