Selection of heat-resistant coating with metalloceramic barrier layer for protection of re-ru-bearing Nickel-based superalloy VZhM4

Selection of heat-resistant coating with metalloceramic barrier layer for protection of details made of Re-Ru nickel-based superalloy operating at 1150°С is made. High-temperature tests of isothermic and cyclic heat-resistance and research of structure after these tests are made. Results show that the Ni–Cr–Al–Ta–Hf–Re–Y barrier layer containing tungsten carbide particles effectively suppresses forming of the secondary reaction zone. Heat-resistant coatings for Re-Ru superalloy reduce corrosion level up to a dosens of times.

Directions for development of heat-resistant carbon fiber reinforced plastics on ba-sis of polyimide and heterocyclic polymers

The main tendencies of development of receiving high-temperature polymeric com-posite materials, in particular carbon plastics are considered. Perspective types of the polymers, allowing to provide heat resistance to 400°С and technologies of receiving products on their basis are considered. The main directions of development of PCM on the basis of polyimide, bismaleimide resin and the phthalonitrile binding are revealed. The works which are carried out to Federal State Unitary Enterprise «VIAM» for re-ceiving heat resistant carbon plastics are provided.

Review of methods for determining the quality of the structure of single-crystal castings from superalloys

Quality control in industrial production level is determined and provides the properties and characteristics of the final product. In such a high-process as the production of single crystal articles, quality control becomes particularly important. X-ray diffraction methods for studying the structure of crystals are the perfect advanced technologies that allow for fast, accurate and simple enough control of single-crystal products at various stages of production. The article provides an overview of existing modern X-ray diffraction techniques to control, analyze their weaknesses and make recommendations to optimize process con-trol of single crystal castings.
