Application of Fe-P-B alloys in developing wear-resistant composite materials

Structures and properties of alloys, which belong to the Fe3(P,B)-Fe5PB2-Fe2P, Fe2B-Fe3(P,B)-Fe5PB2, Fe2B-Fe3(B,P)-Fe3(P,B), and Fe-Fe3(P,B)-Fe3P concentration triangles of the Fe-P-B phase diagram have been studied. To produce composite materials for operation under the conditions of abrasive wear at increased temperatures, a Fe-12P-1B alloy has been recommended as a filler. The formation regularities of the structure and properties of interfaces between the Fe-12P-1B filler and copper-based binders in composite materials produced by infiltration have been defined.
