随着增材制造技术的不断发展,钛合金材料在航空航天、医疗器械、汽车等领域得到了广泛应用。然而,增材制造过程中的热处理和快速凝固等因素会导致钛合金材料的微观结构和性能发生变化,从而影响其耐腐蚀性能。因此,对于增材制造的钛合金材料,需要进行电化学临界局部腐蚀温度(E-CLCT)的测量,以评估其耐腐蚀性能。

ISO 22910:2020 标准规定了测量增材制造的钛合金材料的E-CLCT的方法。该标准要求使用电化学工作站进行测量,包括电化学腐蚀电位扫描和电化学阻抗谱测量。在测量过程中,需要控制温度和电解液的成分和浓度,以确保测量结果的准确性和可重复性。

ISO 22910:2020 标准适用于各种增材制造方法制造的钛合金材料,包括激光熔化、电子束熔化、电弧增材制造等。该标准的实施可以帮助制造商评估钛合金材料的耐腐蚀性能,优化增材制造过程,提高产品质量和可靠性。
