Dynamic metallization - DYMET Equipment
New innovative
portable equipment for metal spraying.
It allows the deposition of soft metals - aluminium, zinc,
copper, nickel, tin, led, babbit and titanium
to any metal, ceramic or glass surface at low temperature - 120-150°C.

Technology
Dynamic
metallization technology (also known as a metal spraying) is
based on the idea of kinetic bombing of substrate with metal powder
particles. Due to supersonic velocity the particles bond with
the treated surface on subatomic level, which guarantee high adhesion
of interface and high cohesion of a homogenous coating.
|
 |
Unlike
thermal spray processes dynamic metallisation technology operates
almost room temperature.
Cold-sprayed materials experience little or no oxidation during
the process and the coatings show high densities and conductivities.
This fact makes the technology unique. |
Technology
implies surface interaction of metal particles moving at extremely high
velocities with the substrate. This equipment has no analogues in traditional
coating methods.
Attractiveness
of dynamic metallisation method is that the equipment devices and
deposited coatings have no limitations inherent in other metal coating
methods and feature a number of technological, economic and environmental
advantages.
Key
advantages

from surface and atmosphere conditions
Equipment
Our small-size
equipment has different technical applications mainly in assembling,
repair or restoration works. The equipment can be built in automatic
production lines, work posts, sections or robotic systems.
