Problems solved by technology

[0003] At present, some general evaluation methods are mostly used in the research on the influence of surface engineering processes such as seepage layers on mechanical properties, which cannot truly reflect the characteristics of the service conditions of the blades, and no special evaluation methods that fully meet the actual use requirements of turbine blades have been proposed; the existing The technology only focuses on a single performance of the blade, and there is no systematic test and evaluation p

Abstract

The invention belongs to the field of gas turbine blades, and particularly relates to a turbine blade infiltrated layer mechanical property test evaluation method. The method comprises the following steps: 1, demand analysis: determining a concerned part of a turbine blade according to a service condition; and determining a performance analysis index of the turbine blade; 2, test design: designing a test piece design according to the concerned part of the turbine blade, the test piece comprising a standard test piece and a structural feature piece; determining test items and loading conditions of each standard test piece and each structural feature piece according to the performance analysis index of the turbine blade; and respectively testing each standard test piece and the structural feature piece, and acquiring test data; and 3, quantitatively evaluating the single performance and comprehensive performance based on test data. According to the turbine blade infiltrated layer mechanical property test evaluation method, quantitative evaluation of the infiltrated layer mechanical property of the actual use requirement of the turbine blade can be comprehensively reflected.

Description

technical field [0001] The application belongs to the field of gas turbine blades, and in particular relates to a method for testing and evaluating the mechanical properties of a seepage layer of a turbine blade. Background technique [0002] Aeroengine and gas turbine blades work under high temperature and complex load conditions, which put forward higher requirements for their mechanical properties. Corrosion protection should also be considered for aircraft and ship power plants serving in marine corrosive atmospheric environments. The aluminide diffusion infiltrated layer is currently a more commonly used high-temperature corrosion-resistant process, and it has a good application prospect in turbine blades. Based on the existing research data, the infiltrated layer has certain influence on the mechanical properties of parts while improving the corrosion resistance. Therefore, in order to ensure the safety of the turbine blade in service, it is necessary to study and eva...
