APT Detonation spraying D-Gun coating service brief introduction
APT coating provide comprehensive, cost-effective Detonation spraying D-Gun capabilities that allow our customers to improve their operational efficiencies and reduce maintenance costs through our D-gun coatings services.
APT Detonation spraying systems
Due to the high speed of spraying particles, the bonding strength of the coating is high (more than 70 MPa), and the porosity is low (< 1%).
Especially suitable for carbide coating
Less carbon loss and less oxidation of carbide coating with high hardness and high density can be obtained.
ABB Robot manipulation
Fully automated ABB robotics, Dgun can be applied in a uniform, precision manner to spray ; which can otherwise be costly, have long lead times or are obsolete.
Accurate spraying
The micro layer formed) [5-10 μ M] and the necessary scanning of the treated surface
Multifunctional spraying workshop
Equipped with exhaust system, turntable, manipulator, lighting system and measuring system
AME TESTING LABS
APT independent testing laboratory, monitor coating quality and improve process at any time

carbides，such as tungsten carbide or chrome carbide with a variety of metallic binders
metallic alloys such as MCrAlYs
ceramics such as alumina- or yttria-stabilized zirconia and cermets
Typical applications
Electrical insulation coating
Alumina coating coated in thread connection for electrical insulation
Dimension Restoration
Super Wear resistance
Cermet coating such as WC10Co4Cr coating，WC12Co coating， CrC25NiCr coating sprayed by D-Gun process. Compared with other coating processes, it has obvious advantages in wear resistance.
Bronze for steel parts up to 5mm thick
About the D-Gun process technology
- D-gun is the leading solution for parts that require extraordinary wear and mechanical properties.
- It combines gas and powder in controlled detonations to generate outstanding bond strength and density. .
- The gun’s duty cycle includes the following operations:
- -A well opened from one end, filled with explosive gas mixture;
- -Put a piece of powder into the barrel;
- -The explosive mixture burns at the closed end of the gun barrel, which leads to self-sustaining explosion wave;
- -The explosive accelerates and heats the powder, usually up to the melting point;
- -When the powder collides with the particle parts, the powder surface and the powder surface are closely combined to form a coating with a thickness of up to 10 microns;
- -A range of shots is added, during which the parts are moved by the manipulator.
Coating Features:
- Significantly improved coating properties
- Fatigue resistance
Typical Applications:
- Fan blade midspans in aviation engines
- Turbine blade z-notches
- Knife-edge seals in power generation
- Steel-sheet roller guides and extruders.
