Embodiment 1

[0031] (1) Select Fe 78 Si 9 B 13 Amorphous ribbon waste, its XRD test results are shown in figure 1 , it can be seen that it is in a completely amorphous state. The strip is placed in a vacuum tube furnace, which is filled with argon and guaranteed to be an argon atmosphere. The temperature is raised from room temperature to 350 ° C, the heating rate is 20 ° C / min, and the holding time is 2 h. , after the heat preservation is over, the strip material is cooled with the furnace, and the Fe obtained after cooling 78 Si 9 B 13 Amorphous strip waste was detected by XRD figure 2 , indicating that the strip scrap has not crystallized.

[0032] (2) Place 150 g of heat-treated strips in a 2L ball milling jar with a ball-to-material ratio of 20 to 1. After the ball milling jar is sealed, vacuumize and feed argon to ensure that the ball milling jar is an argon atmosphere. Put the ball mill jar on a planetary ball mill for 10 hours, the rotation speed is 400r / min, and the revo...

Abstract

The invention discloses a preparation method of an amorphous coating, belongs to the field of processing of amorphous alloy coatings, and particularly provides a preparation method of an iron-based amorphous alloy plasma spray wear-resistant coating. The method comprises the three steps including amorphous powder preparing, treatment before spray and plasma spray. The obtained amorphous coating is a high-purity amorphous coating and has the beneficial effects of high density, high hardness and high wear resistance.

Description

technical field [0001] The invention belongs to the field of processing amorphous alloy coatings, in particular to a preparation method for iron-based amorphous alloy plasma spraying wear-resistant coatings. Background technique [0002] Iron-based amorphous alloy is a new type of high-tech material, because of its unique structure, excellent material properties, simple and efficient preparation process and extremely broad application prospects. With the deepening of basic research on iron-based amorphous alloys, the maturity of preparation technology and the expansion of product development, various amorphous alloy materials have been widely used. When the development of iron-based amorphous alloy strips is advancing by leaps and bounds, problems also follow. During the production process of iron-based amorphous alloy strips by the single-series planar flow casting method, 10% of the strips before and after the strips are waste strips due to defects such as unilateral, bur...
