Embodiment 1

[0031] A laser cladding boride-based wear-resistant coating comprises the following raw materials in mass percentage: 48wt% of Mo powder, 24wt% of Fe powder, and 28wt% of FeB powder.

[0032] The above-mentioned laser cladding boride-based wear-resistant coating is prepared according to the following steps:

[0033] Weigh raw materials according to the following mass percentages: Mo powder 48wt%, Fe powder 24wt%, FeB powder 28wt%, standby;

[0034] Under the protection of an inert gas, put the raw materials in a planetary ball mill for ball milling, select SiC balls, use the wet milling method for ball milling, and pass in argon as a protective gas to prevent powder oxidation. The specific ball milling parameters are: The ball material ratio is 6:1; the total mass ratio of ethanol to powder is 1:1; the ball milling speed is 260r / min, and the ball milling time is 16 hours; the powder scale distribution after ball milling is uniform, and the size meets the laser cladding powder ...

Embodiment 2

[0041] Same as Example 1, except that the following mass percentages of raw materials are included: Mo powder 50wt%, Fe powder 20wt%, FeB powder 30wt%; the particle size of the coating powder is about 15 μm.

Embodiment 3

[0043]Same as Example 1, except that the following mass percentages of raw materials are included: Mo powder 50wt%, Fe powder 25wt%, FeB powder 25wt%; the particle size of the coating powder is about 45 μm.

Abstract

The invention discloses a laser cladding boride-based wear-resistant coating as well as a preparation method and application thereof, and belongs to the technical field of metal surface treatment. The wear-resistant coating is prepared from the following raw materials in percentage by mass: 45 to 50 weight percent of Mo powder, 20 to 25 weight percent of Fe powder and 25 to 30 weight percent of FeB powder. The wear-resistant coating provided by the invention is applied to wear-resistant tool parts, the surface hardness of the coating is high, the wear resistance is excellent, the service life is greatly prolonged by 5 times or above, and meanwhile, as the coating and a matrix are metallurgically bonded, the condition that the coating falls off cannot occur. In addition, materials used by the coating are low in cost, no high-cost alloy element exists, and the use cost performance is very high.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a laser cladding boride-based wear-resistant coating, a preparation method and an application. Background technique [0002] Friction and wear cause a huge waste of resources and energy. Foreign statistics show that: friction and wear consume 1 / 3 of the primary energy, and about 80% of mechanical parts fail due to wear. Therefore, wear-resistant materials are a very important material, and the comprehensive performance requirements of wear-resistant materials used in industry are getting higher and higher to meet a wider range of applications. Cermet is an excellent wear-resistant material due to its excellent wear resistance and ultra-high hardness. However, bulky metal-ceramic parts are difficult to produce due to process problems and are highly brittle. Contents of the invention [0003] The purpose of the present invention is to provide a lase...
