Abstract

Abstract:

Patankar model has been used on Cu-Zn alloy surface to fabricate bionic coupling structure by means of laser photograph technology. Hydrophilic capacity has been improved 62% or the apparent contact angle decarse from 82.5°to 31.5°. The results show that the relationship between unit character parameter and apparent contact angle does not keep the same step with Wenzel or CassisBaxter model. Distortion exist on linear regress model. Nonlinear math′s model characterizes the relation between unit character parameter and apparent contact angle.

Key words: engineering bionics, Cu-Zn alloy, hydrophibicy, Patankar model, contact angle
