Anti-sticking coating, hard alloy load-bearing boat and preparation method of hard alloy load-bearing boat
The invention belongs to the field of hard alloy burning boat preparation, and discloses an anti-sticking coating and a preparation method thereof.The anti-sticking coating is formed by spraying coating powder to the surface of an object, and the coating powder comprises yttria-stabilized zirconia, chromic oxide, copper, carbon black and graphite flakes according to the mass ratio of 80-90: 3-5: 5-8: 1-3: 1-4. The invention further discloses a hard alloy setter boat and a preparation method thereof, a graphite boat is used as a matrix, and the surface of the graphite boat is coated with the anti-sticking coating. The conditions of boat adhesion, carburization and the like are avoided, so that coating stripping caused by adhesion of a hard alloy product to the surface of the boat can be avoided, and the service life of the anti-adhesion coating is greatly prolonged; and the isolation protection effect of the coating is enhanced, the influence of a spraying layer on the product performance is reduced, and the coating is particularly suitable for high-binding-phase hard alloy (the binding phase content reaches 22% or above) and medium-and-high-cobalt hard alloy.
本发明属于硬质合金承烧舟皿制备领域，公开了一种防粘涂层及其制备方法，由涂料粉喷涂到物体表面后形成，涂料粉的组分包括氧化钇稳定氧化锆、氧化铬、铜、碳黑和石墨鳞片，其质量比为80‑90∶3‑5∶5‑8∶1‑3∶1‑4。还公开了一种硬质合金承烧舟皿及其制备方法，以石墨舟为基体，在石墨舟表面覆有该防粘涂层。避免了粘舟、渗碳等情况，从而可以避免硬质合金产品粘结于舟皿表面而造成涂层剥落，使得该防粘涂层的寿命大大提高；还增强了涂层隔离防护作用，减少喷涂层对产品性能的影响，尤其适用于高粘结相硬质合金(粘结相含量达22％以上)以及中、高钴硬质合金。
