铸铁青铜制造的各种轴瓦在机器制造中用的很多。由于铜的供应比较困难,经常影响到任务的完成,而采用铜合金制造各种轴瓦,成本又很高。所以寻找青铜轴瓦代用的材料就成了一项很紧迫的任务了。我们参考有关资料,进行铸铁轴瓦渗硫的试验,并取得基本成功,已 Various cast iron bronze bearings used in the manufacture of a lot of machinery. Due to the relatively difficult supply of copper, often affect the completion of the task, and the use of copper alloy manufacturing various bearings, the cost is very high. So look for the bronze bearing substituting the material has become a very urgent task. We refer to the relevant information for cast iron bearing sulfur infiltration test, and achieved basic success, has
