澳大利亚研究人员对一寿终(速度和精度下降)镀铬坦克炮管进行了失效分析。在膛内轴对称部位发现局部铬层剥落现象,原因似乎是原先存在于镀层内贯穿至基体钢表面的微裂纹的扩展所致。而发射过程中某些弹的铜弹带的残铜又被挤进这些微裂纹,最
Australian researchers conducted a failure analysis of the end of life (reduced speed and accuracy) chromed tank barrel. Local chrome flaking was found in the axisymmetric part of the bore, due to the expansion of microcracks originally present in the coating penetrating the base steel surface. The firing process of some of the bombardment of some of the shells of copper elastic band is squeezed into these micro-cracks, the most
