Abstract

The invention discloses temperature-control fluid flushing analog experiment equipment in the material property test technique domain, which comprises the following parts: motor, stepless variable device, rotary drum with blade, vertical specimen rack around drum, storage container and thermostatic device, wherein the natural seawater or artificial seawater is injected in the thermostatic device to start pump when the temperature reaches the request; the motor is opened and the drum blade begins to rotate; the moving fluid makes the front-back face of connection the sample on the blade and sample around the drum do flushing operation. The invention can analog ship and sea structure material as well as protective coater against seawater flushing, which is convenient and rapid to estimate the seawater-proof flushing property of new sea material.

Description

technical field [0001] The invention belongs to the technical field of material performance testing. In particular, it relates to a method for testing and evaluating the damage characteristics of ships and marine structures and their protective coatings under seawater corrosion and seawater erosion by simulating the process of ships and marine structures being scoured by seawater and controlling the change of seawater temperature. test device. Background technique [0002] Ships and marine structures are scoured by seawater. At the same time, with the change of air temperature, the temperature of seawater also changes greatly. Under the action of seawater with high temperature and solid particles, the materials are in a complex state and are most prone to damage. invalidated. At present, dynamic seawater corrosion simulation test devices have been established in port marine test stations at home and abroad, and most of them are rotary test devices suitable for dynamic seaw...
