Study of Film Layer Structure and Resistance on High Strength Room Temperature Blackening Yufeng Zhang1a, Xi Zhang1b, Minrui Li1c and Bo Wang 1Wuhan Mechanical Technology College, Wuhan 430075, China ashujia@163.com, bzhangxilu@163.com, cqiangjunzju@163.com Keywords: Room temperatures, Blackening, Film layer structure, Wear resistance Abstract: In this paper, the high strength room temperature blackening film on steel surface were prepared, the structure and the forming principle of the film were studied.
Physics and chemistry data of blackening liquid of the Cu-Se-P system at room temperature: Total acidity 29～38 Points; Swim leave sour 1～3 points; pH 2～3.5; ratio weight (25) 1.05±0.001; color black.
There are many methods to throw off the oil, such as throwing off the oil by chemistry at the normal, middle and high temperature; spraying sand to throw off the oil; rolling light machine to throw off the oil; ultrasonic and electro analysis to throw off the oil; heating to throw off the oil etc.
Surface images were observed by microscope, on the surface of specimen, the blackening layer was the even fine structure that was piled up (see the fig. 1). the structure of the flat surface shape grow up along two direction, and there was something in its gap.
In the process of forming the film, firstly the grain formed on the high emerge place, thereafter, the flat surface sharp structure would formed gradually[2].

In the first case, a HIPS composite was analyzed by EDS to locate the graft copolymer species containing Si atoms, which were previously synthesized by anionic polymerization using chloro-silane chemistry.
These structures overlapped the AgNP´s in the transmission electron microscopy (TEM) images, thus resulting this technique to be inadequate to establish the location of the AgNP´s.
In the first case, this study involves the synthesis of HIPS using a model graft copolymer containing Si atoms, which were previously synthesized by anionic polymerization using chloro-silane chemistry.
The model graft copolymer with 1 PS graft (Mn PB backbone = 72,000 g/mol and Mn PS graft = 115,000 g/mol) was synthesized by high vacuum anionic polymerization using chloro-silane chemistry as described elsewhere [3].

The originality of the method is in the material hydrophobization by introducing polyethylene fibres into the structure of ferrocyanides.
The next stage is the hydrophobization of the material by introducing polyethylene fibres into the structure.
The resulting sorbent is a porous hydrocarbon copolymer, the structure of which includes ferrocyanide Me-K particles.
It has been determined that the phase composition of materials is characterized by the crystal structure of ferrocyanides.

It is well-accepted that the wettability of structured surfaces is governed by surface roughness and interface chemistry properties.
Changing the surface chemistry effectively modifies the surface energy: a lower surface energy a stronger de-wetting property and thus lager contact angles (CAs).
Except for the surface chemistry, the roughness plays more important role on the wettability.
