METHOD OF MAKING A POWDER PARTICLE FOR PREPARATION OF A FINE-GRAINED HARD MATERIAL ALLOY |
摘要 |
<p>The present invention relates to powder particles consisting of hard principles and binder metal for the manufacture of superior, uniquely fine-grained hard material alloys and to a procedure for the preparation of said particles. The preparation is performed in an economical way because the procedure starts from conventional melt metallurgical raw materials. A pre-alloy consisting of hard principle forming and binder phase forming elements is subjected to a heat treatment such as nitriding and carburizing after being crushed. The final product is particles composed by hard principle phases and binder metal phases formed "in situ" in an effective binding.</p> |
