The general characteristics of the process include: – the efficiency of 20-30% of the material – the speed of the coating from 0.2 to 0.8 kg / h – layer thickness from 100 microns to 50 mm – material of the substrate for the deposition – all metals and ceramics. The most common properties of the coatings include: – adhesion of 20 to 80 MPa, – a tensile strength from 50 to 120 MPa – porosity of 3-5% – Brinell hardness of 100-1600 MPa, – elongation of 1-2%. There are currently more than a dozen kinds of powder materials for coating based on aluminum, copper, zinc, nickel, tin and lead. All of these powders can be applied in different modes and different nozzles. It is possible to get a wide variety of coating properties. Nevertheless, they are mainly characterized by the above common properties. Equipment can not be applied DIMET hard and wear-resistant coating.
Heat-resistant coatings provide protection up to 1000 1100oS. Electrical conductivity is on average 80-90% conductivity of the bulk material. The corrosion resistance depends on the characteristics of an aggressive environment. Uniqueness of the technology spray (also known as the specialists of "capacity" of the metal) is low temperatures falling to the substrate particles is not higher than the temperature of the engine car. In this case, interact with the solid substrate particles in the unmelted state, but have very high speed. Use of equipment DYMET has several advantages over traditional methods. These advantages are as follows: coating is applied in air at normal pressure, for any values of temperature and humidity of the air, with the coating is negligible thermal effect on the coated product, coating technology is environmentally friendly (No high temperature, radiation and hazardous gases, not chemically aggressive waste requiring special neutralization) does not need heating surface application, if there is no rust or scale on the product does not require special surface preparation, since the high particle flux cleans the surface of the technical dirt, oils, paints and activation of the crystal lattice of the material goods, because the flow of particles is highly directional and has a small cross section, in contrast to traditional gas-thermal spraying methods, we can apply coatings to the local (with clear boundaries) surface areas of products; possible to apply a multi-component coatings with varying content of components of its thickness, the equipment is compact, mobile and technically available for virtually every industrial enterprise can integrated into automated production lines, does not require highly skilled personnel for its operation, a simple change of technological regime allows mikroerozionnuyu (jet-abrasive) treatment surface for subsequent coatings or to achieve decorative effects, possibly causing different types of coatings by means of a single unit, as most models have two DYMET bulb under the powder; may be using equipment in the field.
