Electric arc metallization (ASP)
Electric arc metallization method consists in application of coatings by melting particles of two consumable electrode wires, between which electric arc burning occurs, and further transfer of molten particles by compressed air to surface of part (substrate).
Purpose:
- corrosion protection by applying coatings made of zinc, aluminum, stainless steel and their alloys;
- protection of parts against wear;
- creation of decorative coating by spraying brass, copper, bronze and other materials.
Advantages:
- equipment mobility, which makes it possible to apply the coating directly during the facility operation or without equipment dismantling;
- the equipment is simple to operate, does not require complicated maintenance and expensive maintenance;
- High process productivity and low operating costs, allowing coating to be applied to large objects and large areas
- effective corrosion protection of metal structures; anticorrosive coatings obtained by electric arc metallization have a protector property;
- the use of oxygen, kerosene or combustible gas is not required, which reduces the coating cost;
- using two different wires to produce a pseudo-alloy coating during metallization;
- a safe process;
- can be used in manual or automated mode.
Application:
- bridges, roads and utilities;
- shipbuilding and hydraulic construction;
- oil and gas;
- chemistry and recycling;
- energy.
