摘要
提出用无压渗透法制备铸造表面复合材料的新方法。通过预先制备带有孔隙的硼铁合金预制块，用普通浇注的方法，获得以灰铸铁为基的铸造表面复合材料。复合层从化合物层到亚共晶层的厚度达８ｍｍ，其组织和硬度由表层向基体呈梯度分布。
A pressureless permeating method is put forward. Using a prefabricated porous ferroboron lump, a surface composite layer was made on gray cast iron matrix, with a common casting method. The thickness of the surface layer is 8mm; the hardness and microstructure change gradiently. Sliding wear test shows that the wear resistance of the composite surface is higher than that of Cr12 type high chromium cast iron.
