Tantalum carbide coating, preparation method of tantalum carbide coating, carbonaceous structural member and application of carbonaceous structural member
The invention relates to a tantalum carbide coating, a preparation method of the tantalum carbide coating, a carbonaceous structural member and application of the carbonaceous structural member, and the preparation method of the tantalum carbide coating comprises the following steps: mixing tantalum carbide particles, a sintering aid, an adhesive and a solvent to obtain turbid liquid; wherein the sintering aid comprises at least one of transition metal carbide and a mixture containing transition metal elementary substance and carbon powder; and coating a substrate with the turbid liquid, carrying out pre-warming treatment at the temperature of 100-400 DEG C under a vacuum condition, and carrying out sintering treatment at the temperature of 1800-2500 DEG C under a protective atmosphere to form the tantalum carbide coating. The method is simple in process and low in cost, and the prepared tantalum carbide coating is not prone to cracking and reliable in quality. When the coating is applied to a high-temperature process, the temperature resistance, the chemical stability and the corrosion resistance are better, and the pollution to the process caused by the problems of cracking of a coating on the surface of a structural part and the like can be avoided.
本发明涉及一种碳化钽涂层及其制备方法、碳质结构件及应用，该碳化钽涂层的制备方法，包括以下步骤：将碳化钽颗粒、烧结助剂、粘接剂与溶剂混合，获得悬浊液；其中，烧结助剂包括过渡金属碳化物以及含有过渡金属单质和碳粉的混合物中的至少一种；将悬浊液涂覆于基底上，于100℃～400℃及真空条件下进行预温处理，于1800℃～2500℃及保护气氛下进行烧结处理，形成碳化钽涂层。该方法工艺简单、成本较低，制得的碳化钽涂层不易产生裂纹、质量可靠。应用于高温工艺中时，耐温性、化学稳定性和耐腐蚀性较好，还可避免因结构件表面涂层的开裂等问题造成对工艺的污染。
