Research of surface coating solution for bead wire

Due to the PET bottle which are applied for the special requirement of bear packing, so this paper briefly described the obstructing technology of PET and the relative research progress, mainly included surface coating technique, co-compounding or copolymer、oxygen clean up agent、multi- layer complex and nano technology.

Surface coating is one of effective methods for preparing carbon molecular sieve membrane (CMSM ).

This article describes the classification, technology tendency, industrial status and market distribution of coat fabrics in detail.

In this paper,coating interface microstructure of TA7 titanium alloy,which was coated by the metal molybdenum with spraying in the argon atmosphere and then kept at high temperature diffusing,was analyzed with microscope,scan electrode microscope,electrode probe and X-ray diffraction etc.

Using the finite element method,the paper presented the model for analyzing the mechanic behavior of two-dimensional elasto-plastic contact with multi-asperity coating surfaces,and simulated the elasto-plastic contact of rigid surfaces with rough surfaces with varying moduli of elasticity,yield strength,coating thickness and surface topography.
