一问:铁基粉末冶金结构零件的技术条件一般包括哪些项目? 答:在确定铁基粉末冶金结构零件的技术条件时,必须考虑到粉末冶金材质有孔隙及生产过程的工艺特点,因此仅仅规定材料种类(甚至只给出材料的配比)是不够的。尤其在铁基粉末冶金结构材料标准(JB2797—81)尚未被人们普遍接受的情况下,更需要在烧结结构零件的技术条件中明确规定影响使用性能的各项技术指标,以满足设计要求和保证使用的可靠性。铁基烧结结构零件的技术条件通常包
A: The technical conditions of iron-based powder metallurgy structural parts generally include the project? A: In determining the technical conditions of iron-based powder metallurgy structural parts, must take into account the powder metallurgy material porosity and process characteristics of the production process, so only provisions The type of material (or even only the material ratio) is not enough. Especially in the iron-based powder metallurgy structural materials standards (JB2797-81) has not been widely accepted, but also need to specify the technical conditions in the sintered structural components affect the performance of the technical indicators to meet the design requirements and assurance The reliability of use. Iron-based sintered structural parts of the general conditions of the package
