Detonation spraying is one of the many forms of thermal spraying techniques that are used to apply a protective coating at supersonic velocities to a material in order to change its surface characteristics. This is primarily to improve the durability of a component.

2024年7月19日 · A detonation gun (D-gun) is device that can deposit a variety of materials and ceramic coating at supersonic speeds onto a workpiece by controlled detonation of oxygen and acetylene. It is used in the thermal spraying process for providing hard, wear-resistant and dense-microstructured coatings.

D – gun thermal spray, also known as detonation – gun thermal spray, is a high – velocity thermal spray process. It uses the energy of a detonation wave to accelerate and deposit coating materials onto a substrate.

2023年10月15日 · In this work, a WC-12Co coating was fabricated by the detonation gun (D-gun) spraying. Its microstructure, mechanical properties and tribological behaviors under FLiNaK molten salt were systematically studied. The main conclusions are drawn as follows. (1)

2019年10月15日 · Al 2 O 3 -SiC powder mixture can be successfully deposited on bond coated steel by D-Gun technique without decomposing SiC. Al 2 O 3 ‐3 wt% SiC coating is found to be the highest wear resistant material among the selected Al 2 O 3 -SiC coatings.

The detonation spray coating (DSC) process is a variant of thermal spraying in which powder feedstock of the coating material is heated and accelerated by high-pressure, high-temperature gaseous products resulting from controlled explosive combustion of a carefully measured mixture of gases (usually oxygen and acetylene), to impact a substrate a...

D-gun thermal spray coating is a thermal spray coating process that uses a detonation gun to combine gas and powder in controlled detonations. This process generates outstanding coating bond strength and coating density, making it the leading solution for parts that require extraordinary wear performance and mechanical properties.
