Method and device for acquiring environmental sensitivity of metal material

Abstract

The invention discloses a method and device for acquiring environmental sensitivity of a metal material, and the method comprises the steps: building a correlation sequence of corrosion data and environmental data of each test station according to the metal corrosion data and environmental data of each test station; based on the association sequence, carrying out equalization processing, and calculating the association degree between the corrosion data of each test station and the environmental data; constructing a comparative judgment matrix based on the correlation degree, and calculating the weight of the metal material of each test station for different environmental factors; and after the consistency check of the comparison matrix is passed, taking the weight of each environmental factor as the sensitivity of the metal material to different environmental factors. The method solves the problem that the corrosion degree of the metal material caused by marine atmospheric environment factors can only be qualitatively analyzed and compared but cannot be quantitatively calculated in the past; according to the method, the problems of long time consumption, high expenditure and the like in research of material corrosion characteristics under actual marine atmosphere service conditions in the past are solved.

Description

technical field [0001] The invention relates to the technical field of protection of metal structural parts, in particular to a method and device for acquiring the environmental sensitivity of metal materials. Background technique [0002] During the service period of marine metal structural parts, the marine atmospheric environment is complex and changeable, and the marine environment in different sea areas and seasons is also different. Marine structural metal materials have been in service for a long time in the dynamic alternating movement across the sea area, and the exposure environment is also dynamic alternating and multi-factor comprehensive effects, coupled with the influence of various marine mechanical loads, the corrosion damage and abrasion failure of the material are inevitable, and the environment and The damage pattern and corrosion mechanism of the material are also different under different loads. The main factors affecting marine corrosion are temperatur...
