高速钢刀具磷化处理试验研究

为了探索磷化处理对高速钢刀具寿命的影响情况,采用不同工艺规范的磷酸锌盐快速热磷化和马日夫盐热磷化处理刀具,通过比较经磷化处理的刀具与未磷化处理的刀具的切削情况和耐蚀性能,得知磷化处理可以提高金属切削刀具的寿命和抗腐蚀性能.介绍了磷化膜质量检验的方法,重点分析了磷化处理工艺过程中,零件表面粗糙度、钢的合金元素、显微结构、磷化液温度、酸度、磷化时间等因素对磷化处理的影响.通过对磷化处理提高刀具寿命和抗蚀性能的机理分析,得到磷化处理提高刀具寿命和抗蚀性能的原因是:磷化膜导热性能差,不易使刀具切削刃升温,同时磷化膜改善了刀具表面的润滑条件.

Green chemistry in situ phosphatizing coatings

The current organic coating on metals for aerospace applications involves a multi-step process and considerable energy, labor and control, and it generates toxic wastes such as chlorinated solvents, cyanide, cadmium, lead and carcinogenic chromates. The green chemistry technology of in situ phosphatizing coatings (ISPCs) developed in our laboratory is a one-step self-phosphating process, in which the deposition of metal phosphate layer on the substrate surface and the curing of polymer paint film take place independently, but simultaneously. The formation of a metal phosphate layer in situ will essentially eliminate the metal surface pre-treatment step of employing a phosphating line/bath. The use of chemical bonds linked to the paint polymers to seal the pores of metal phosphate in situ should enhance coating adhesion and suppress metal corrosion without a post-treatment of final rinses containing chromium (Cr⁶⁺). The successful applications of ISPCs in three types of commercial paints (solvent-borne high-solids, water-reducible and VOC-free latex) on bare and pre-treated cold-rolled steel and 2024 aluminum coupons is presented. The protective performance (coating adhesion and corrosion inhibition) of ISPCs is shown to be superior over that of the current multi-step coating practice.     

锌系磷化废水去锌除磷的研究

以Fe3（SO4）2和CaCl2为沉淀剂处理磷化废水,研究废水中锌对磷化溶液化学特性的影响。结果表明,当进水TP（总磷）浓度为15．67mg／L,不加任何沉淀剂,以NaOH调节pH到12．10,处理后出水磷浓度为9．53mg／L;采用Fe3（SO4）2为沉淀剂时,进水磷浓度为11．97mg／L,出水磷浓度为0．44～O．26mg／L,除磷的最佳pH范围为3．04～5．50;改用CaCl2沉淀剂,进水磷浓度为12．24mg／L,出水磷浓度小于0．47mg／L,除磷的pH大于10．72,除锌pH大于8．00,因此在碱性条件下,能同时达到除磷和除锌的要求,处理后出水达标排放。
