| 摘 要： | 研究了等离子喷涂碳化硼涂层在不同能量密度的激光辐照下的耐热冲击与热蚀行为。结果表明：碳化硼涂层有较好的抗激光辐照熔融能力和耐热冲击性能。气孔率是影响碳化硼涂层抗热冲击能力的重要因素。在相同实验条件下，较低气孔率的涂层具有较大的热导系数和耐热冲击能力。

| Abstract: | Thermal shock behavior of plasma sprayed boron carbide coatings was studied. The result shows that the boron carbide coating has good thermal shock resistance under laser irradiation. Porosity was a key factor affecting thermal shock resistance. Under the same experimental conditions, the lower the porosity of boron carbide coating, the more strong is the thermal shock resistance. |
