preparation example Construction

[0026] Attached Figure 1~2 , The preparation method of a tungsten boride series thermal spray coating material according to the present invention, the preparation method specifically includes the following steps:

[0027] The first step ingredients:

[0028] The adding ratio of WC powder is 30%~80%, WB n The addition ratio of powder is 10%-45%, and the addition ratio of metal powder M is 5%-30%;

[0029] The amount of binder added is WC powder, WB n 0.5 to 6.0% of the total mass of powder and metal powder M, and the solid-to-liquid ratio (the ratio of the mass of solid raw materials to the mass of liquid deionized water or alcohol) is controlled between 2.75 and 3.25;

[0030] The second step wet grinding and spraying:

[0031] Following the previous step, place the prepared materials in a ball milling tank, use deionized water or alcohol as the ball milling medium, control the ball-to-material ratio in the range of 2:1-8:1, and control the milling time between 12h and 72h , After th...

example 1

[0039] (1) Ingredients: the addition rate of WC powder is 60%, the addition rate of WB powder is 30%, and the addition rate of metal powder Co is 10%;

[0040] (2) Wet milling and spraying: Place the prepared materials in a ball milling tank, use deionized water as the ball milling medium, and after a certain period of ball milling time, the slurry is granulated by spray drying tower;

[0041] (3) Sintering: place the spray-dried powder in a graphite crucible, sinter it at an appropriate sintering temperature, and take it out after keeping it warm for a period of time;

[0042] (4) Crushing and sieving: the sintered powder is crushed and then sieved. The SEM morphology of the powder after screening is shown figure 1 .

Abstract

The invention discloses a preparing method and application of a tungsten boride thermal spraying coating material, and relates to the technical field of materials. According to the preparing method and application, due to the adding manner of tungsten boride, the mobility and the apparent density of thermal spraying powder are improved, and the hardness, the abrasive resistance, the corrosion resistance and the basal-body bonding strength of a coating are greatly improved; HV0.3 is larger than or equal to 1,350; and compared with a conventional thermal spraying material, the overall performance is obviously improved, and the produced tungsten boride thermal spraying coating material has the wider application range and the higher market competitiveness. The preparing method and application are safe and reliable in application and particularly suitable for various coating materials.
