Coating wear-resistant and impact-resistant comprehensive performance evaluation device and method

Abstract

The invention discloses a coating wear-resistant and impact-resistant comprehensive performance evaluation device and method. The evaluation device comprises a bottom plate; a soil test box which is arranged on the bottom plate, and is used for being filled with simulation test soil; a rotating device which is arranged on the bottom plate and comprises a driving system and a rotating system, wherein the driving system provides power for the rotating system; a lifting device which is arranged on the bottom plate and is used for lifting the rotating system of the rotating device; and at least two multi-specification coating samples which are mounted on the rotating system of the rotating device, extend into the soil test box and can perform autorotation and planetary motion along with the rotation of the rotating system. According to the coating wear-resistant and impact-resistant comprehensive performance evaluation device and method, actual working conditions can be simulated more accurately, and the surface coating performance of the agricultural machinery buried part can be evaluated.

Description

technical field [0001] The invention relates to a detection and evaluation technology for surface functional materials, in particular to an experimental evaluation device and method for the comprehensive performance of wear resistance and impact resistance of the surface coating of agricultural machinery embedded in the soil. Background technique [0002] The soil-piercing parts of agricultural mechanized equipment such as plowshares, rotary tillers, and disc harrows directly contact and rub against soil and sand during operation, resulting in severe wear, or impact fracture, causing early failure. In order to improve the wear resistance and impact resistance of buried parts, surfacing welding, cladding and other technologies are commonly used to prepare surface coatings at home and abroad, but there is a lack of experimental evaluation devices and methods that can simulate actual working conditions under laboratory conditions. Conducting evaluation experiments directly in t...

AI Technical Summary

Problems solved by technology

Conducting evaluation experiments directly in the field is greatly affected by factors such as seasons and climates, and the field experiment period is long, the cost is high, and the soil conditions during the evaluation process are inconsistent, resulting in the inability to obtain accurate and effective data

The dry rubber wheel abrasive wear test method or the wet rubber wheel abrasive wear test method usually used in the laboratory cannot evaluate the impact performance of sand and stones in the soil. The experimental results are far from the actual application and cannot effectively guide high reliability. Optimum design and production engineering application of non-toxic coating
