Materials

Natryskiwanie cieplne, ceramika techniczna, naddźwiękowy natrysk HVOF.

The technology of thermal spraying offers a big choice of materials nowadays. Their selection depends on an applicationworking conditions and operation of parts and equipment.
Our employees, often working in consultation with our Customers, select a material for a specific application basing on knowledge and experience gained.
Please note that we use materials from manufacturers that have worldwide reputation.
