论文摘要
为了减少加压水反应堆（PWRS）初级电路中的钴，正在研究和开发耐磨损的钢。特别是感兴趣的是对累积机制的理解，这是一种粘合剂磨损机制，在PWR阀中尤为普遍。在这里，我们表明，在抗折期间，即使在相对较低的压缩应力为50 MPa的相对较低的压缩应力下，也可以利用304升和316升不锈钢之间的2 wt％锰差，从而发生较大的剪切应力和粘合剂转移。通过这些发现，可以更好地理解不锈钢的胆汁机制，这可能有助于开发耐药的不锈钢。
In order to reduce cobalt within the primary circuit of pressurised water reactors (PWRs), wear-resistant steels are being researched and developed. In particular interest is the understanding of galling mechanisms, an adhesive wear mechanism which is particularly prevalent in PWR valves. Here we show that large shear stresses and adhesive transfer occur during galling by exploiting the 2 wt per cent manganese difference between 304L and 316L stainless steels, even at relatively low compressive stresses of 50 MPa. Through these findings, the galling mechanisms of stainless steels can be better understood, which may help with the development of galling resistant stainless steels.
