Plasma Spray - Plasma Electric Arc
Plasma Electric Arc spray process provides a heat energy to reach melting points of ceramic chemistries. This versatile system used at ASB Industries is designated for most ceramic processing providing high temperature, extreme wear and an inert chemical resistant coating to protect components in some of the most severe environments.
Plasma electric arc process is an established thermal spray process very commonly used for numerous applications in many industries, such as aircraft turbine engines and land based turbines that continue to push high temperature protection for greater operating efficiencies. In the chemical industry chemical corrosion, abrasive wear, erosion and cavitation are common wear problems solved by the application of ceramics using the plasma spray process.
When electrical current becomes an issue, a plasma electric arc spray applied ceramic coating has the ability to shield current from passing through critical components causing arcing giving the part dialectrical strength. With added protection, components are shielded from possible severe electrical corrosion wear, damaged bearing components and better part production.
During the spray processing, documented procedures are recorded for each job along with on-going inspections for each critical step. Both the plasma control panel along with our closed loop powder feeders are set at optimized parameters to produce consistent coating quality. All equipment is calibrated to ISO standards to optimize injection of powder into the plasma jet to allow proper melting of powdered materials. All lot numbers from our powder suppliers are recorded and in most cases, sample pieces are placed in the process during production spraying.
Aluminum oxide, chrome oxide and zirconium oxide are common materials applied using the plasma spray process. Thickness specifications are based on the component application including wear and corrosion environments. Along with multilayered coating systems, ASB will utilize specialized sealing treatments to optimize coating performance.
