Detonation gun Plakart Ob D2

Plakart Detonation gun
Plakart detonation gun

Function. The Ob D2 equipment – a new generation computerized detonation system. The device is designed for depositing wear-resistant, heat-resistant, anti-corrosion and other coatings from following powders:

  • metals (copper, nickel, molybdenum, iron and others);
  • alloys (steel, nichrome, bronze and others);
  • oxides of aluminum, chromium, zirconium, titanium and others;
  • metal-ceramic composites with carbide of tungsten, chromium, titanium, etc;

The coatings are applied on the surfaces of metals, ceramics and plastics.

The Ob D2 equipment has a compact modular design and is characterized by high-precision system of the gas supply, dosed local powder supply and computer-controlled gun with vertical movement of the gun manipulator. Application of 1-2 powder feeders allows to generate multilayer composite coatings and mixed layer with required proportion of components. Made in Russia.

Formation of detonation mix is based on acetylene (propane-butane) and oxygen.

Composition. The equipment consists of a mobile detonation gun, the gas preparation unit and cooling system, the control panel based on industrial controller. Significant noise exposure from the equipment during the deposition process requires a sound cabin.
