Description
Technical Field
The application belongs to the field of salt coating high-temperature tests, and particularly relates to a high-flux automatic salt coating device and an operation method thereof.
Background
The hot corrosion is a corrosion phenomenon generated by the combined action of a base metal, precipitated salt (mainly Na2SO 4) deposited on the surface of a machine part and the machine part and gas when a metal material works at a high temperature, and is early called as 'sulfuration corrosion'. During operation of a gas turbine engine, oil and gas combustion products are corrosive and hot corrosion becomes a major failure mode for turbine blades.
The salt-coated high-temperature corrosion test is an effective test method for simulating the hot corrosion process of a material and evaluating the heat-resistant corrosion performance of the material, and the main test process is as follows: and weighing the cleaned sample, coating the prepared salt solution on the surface of the sample, drying, weighing, determining that the salt coating amount meets the requirement, and taking out the sample in a heating furnace for heat preservation for a specified time, so that the heat and corrosion resistance of the material is evaluated through the changes of parameters such as appearance, weight, mechanical property and the like of the sample after corrosion in a periodic test. The hot corrosion resistance of a material is directly related to the amount of salt deposited per unit area of its surface. The greater the amount of salt deposited per unit area, the more severe the effect of hot corrosion. Therefore, uniform application of the salt solution to the sample surface is a necessary condition for the reliability of the test results.
The mechanical property samples are typically circular in cross-section, such as fatigue bars, tensile bars, creep (sustained) bars, and the like. And researching the influence of hot corrosion on the mechanical properties of materials, the working section of a mechanical property sample needs to be uniformly coated with a salt film. However, the round section bar-shaped sample is not easy to uniformly coat salt on the working section of the test bar because the salt film gathers and flows along the surface of the sample and even falls on the surface of the sample under the influence of gravity due to the curvature of the surface.
Patent 201420585576.4, "a salt coating device," describes a salt coating device. The device samples rotate at a constant speed, and the hollow spray pen with the material cup drops salt on the surfaces of the samples. The salt coating nozzle of the device is handheld, is greatly influenced by personal operation, and is not beneficial to uniformity and stability of salt coating; the salt mist is blown out by the air pump, the granularity of the blown salt mist drops is not easy to control, and the uniformity of the salt coating on the surface of the sample is affected; only one sample can be coated at a time, and the efficiency is low.
Patent 201620271366.7, "a gas atomization salt coating device," describes a salt coating device. The device can only be coated on the surface of a sheet sample, but cannot be coated on the surface of a circular section sample; the salt mist is blown out by the air pump, the granularity of the blown salt mist liquid drops is not easy to control, the uniformity of coating salt on the surface of a sample is affected, and only one sample can be coated at a time; and if a plurality of sheet samples are coated at one time, the sample coating amount on the center line of the nozzle is high, the sample coating amount is smaller closer to the edge, and the coating amount difference between the samples is larger.
Therefore, how to improve the salt coating efficiency of a plurality of samples and to improve the automation procedure is a problem to be solved.
