Abstract

Depositing dense or bulk-like superhigh-temperature boride ceramic coatings by thermal spraying is a challenging but attractive method for applications in the electronics industry due to the excellent electrical and thermal conductivity of the resulting coatings. Herein, a dense TiB₂ coating deposited by plasma spraying was investigated by modifying the characteristics of the plasma jet in a controlled environment chamber. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy were used to analyze the phase and microstructure of the sprayed coating. The coating was then used as the negative electrode for a lithium-ion battery. The results showed that a dense TiB₂ coating with fully bonded lamellae was obtained with an Ar/He plasma jet under a very low pressure, resulting in a porosity of 3.05%. A coarse coating with many unmelted particles was deposited with an Ar/H₂ plasma jet under a low pressure. The dense coating with a low electrical resistivity (1.17 × 10⁻³ Ω cm) presented charge/discharge performance, but its specific capacity of 17.22 mAh g⁻¹ requires improvement.

低压等离子喷涂致密TiB2层及其作为锂离子电池负极的探索应用

通过热喷涂沉积致密或块状的超高温硼化物陶瓷涂层是一种具有挑战性但具有吸引力的方法，因为所得到的涂层具有优异的导电性和导热性。在可控环境室中，通过改变等离子体射流的特性，研究了等离子体喷涂致密TiB2涂层。采用x射线衍射、扫描电镜和透射电镜对涂层的物相和显微组织进行了分析。该涂层随后被用作锂离子电池的负极。结果表明：在极低压力下，用Ar/He等离子体射流获得了致密的TiB2涂层，层片完全结合，孔隙率为3.05%；用氩/氢等离子体射流在低压下沉积了一层含有许多未熔化颗粒的粗涂层。致密涂层具有低电阻率（1.17 × 10−3 Ω cm）的充放电性能，但其比容量为17.22 mAh g−1，有待提高。
