PWR plates with plasma transferred arc wear-resistant welding
The product is made as bimetal wear-resistant plates consisting of the base and wear-resistant and erosion-resistant layer. The base is produced of welding (low-carbon, corrosion-resistant or heat-resistant) steel. The wear-resistant layer is applied through plasma transferred arc welding.
Tungsten carbides contained in the built-up layer present an optimal solution for combined protection against abrasive and erosive wear. The plasma transferred arc welding process currently presents one of the most advanced coating application technologies. The built-up layer is characterized with minimal interfusion with the base metal (5% to 8%). PWR plates may be welded, screwed and otherwise retained.
