Highperformance martensitic stainless steel nanocomposite powder for ...
The parameters of ball milling process are shown in Table 1 (where BPR is ball to powder ratio). In order to make nanoWCCo particles evenly attached on the surface of 420 stainless steel, the ball milling process adopts the form of positive and reverse alternation, and stops for 10 min after 30 min positive rotation and then reverses for 30 min.
