The paper deals with the solution of a topical problem of selecting protective ceramic materials to improve the service life of parts of gas-and-oil and other equipment that experience abrasive erosion. The available theoretical and experimental methods of specifying protective materials are analyzed. The author discusses the potential of the energy concept of the abrasive erosion process and uses this concept together with system approach methodology to propose new numerical characteristics. The possibility of determining these characteristics for ceramic materials by the calculation-experimental method involving a developed technique and device is shown. The availability of adequate numerical characteristics of the abrasive-containing flow and the ceramic material forms the basis for selecting a ceramic material using the criterion of its minimal wear intensity in the contaminated flow of a working fluid. The development of a database of generalized characteristics N=f(B) of ceramic materials, provided that quantitative information on the abrasive-containing flow in the form of Gefis available, will allow one to substantiate, using calculations, the application of a protective ceramic material in polymaterial structures of parts and to estimate their predicated life. The use of monolytic ceramic members on the areas of parts which are most subject to AE (Abrasive Erosion) holds promise. This conclusion is based on the application of ceramics to protect such members of gas-and-oil pipelines as valves, taps, etc.
