Introduction Cold-rolled steel is widely used in the manufacture of automotive materials,home appliances and various engineering machinery.In order to have good corrosion resistance and have a strong binding force with the outer coating , the main method is carried out using a chromate or phosphate treatment on its surface[1].However , the hexavalent chromate is toxic and carcinogenic,the phosphorus of phosphate processing is the culprit causing eutrophication.And both methods need to be at 50 ℃ and the energy consumption is relatively large.It has been unable to meet the requirements of environmental protection of modern industry , and therefore sought the metal surface pretreatment technologies of energy saving is very important.

Bone-like apatite layer is a key substance to bring about direct bonding of artificial materials to living bone.
Materials and Methods Polyamides shown in Fig. 1 were prepared according to a literature method [4].
Organic polymers modified with sulfonic groups and calcium chloride are candidate materials to produce apatite-polymer hybrids.
