Microplasma surfacing on turbine blades

Abstract

In modern technologies for the production of turbine blades, plasma surfacing processes of various levels of automation are increasingly used. Plasma surfacing is applied to the working surfaces of critical parts in order to obtain zones with special physical and mechanical properties or restore the specified geometric dimensions, correct defects in the base material, etc. The design of the turbine blades must meet all the requirements of the product’s service life, including long-term strength and creep, anti-friction characteristics under shock and alternating loads, corrosion resistance in fuel combustion products, etc. Plasma surfacing can help meet these requirements.
