Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The pretreatment involved in the specific embodiment of the present invention is as follows:

[0024] Put the sample into the organic solvent acetone or metal cleaning agent for ultrasonic cleaning to remove the oil and impurities on the surface. Finally, wash with deionized water, dry, and set aside.

[0025] After the degreasing treatment is completed, the specific surface processing steps are as follows:

[0026] First, fix the 316L stainless steel that has been degreased on the machine tool, and then set the process parameters of ultrasonic rolling processing. The main parameters are: processing line speed 2m / min, step distance 0.08mm, pressure 1MPa, pneumatic ball, rolling 5 Second-rate. Then, start the power switch, and perform ultrasonic rolling treatment on the surface of 316L stainless steel. The surface of 316L stainless steel after ultra...

Abstract

The invention discloses a method for inhibiting scale on the surface of a blunt metal material. The method comprises the following steps that firstly, a sample is subjected to surface oil removal treatment; secondly, ultrasonic surface rolling machining is conducted; and finally, rolling surface protection is implemented, so that the surface of the blunt metal material is kept in the machining state for service use. The method has the advantages of favorable scale inhibition effect, lower cost and simple preparation, and can well overcome the defects of high cost, complexity, severe partial pollution and the like in the traditional scaling method.

Description

technical field [0001] The invention relates to the technical field of metal material surface treatment application, in particular to a method for inhibiting scale on the surface of passive metal materials. Background technique [0002] Scaling will inevitably occur on the surface of petroleum pipelines, heat exchangers, boilers and other equipment composed of metal materials during service. This is mainly because during the use of metal equipment, the original material balance is broken due to changes in medium temperature, pressure, components, etc., so that scale-forming ions produce crystal grains through crystallization, and grow into dirt after long-term accumulation. . Generally speaking, CaCO is the main component of the fouling 3 Mainly scale, also mixed with MgCO 3 , CaSO 4 , MgSO 4 Wait. After scaling occurs on the surface of metal equipment, if it is not cleaned in time, it will bring a series of problems. For example, after scaling occurs in oil field gath...
