Experimental study on the adhesion properties of Zn-Al metal spray method for steel structures

Abstract

Examination about sticking intensity security way of normal temperature metal spraying covering is required compulsorily accordingly with quantitative assessment about steel plate's surface roughness to secure adhesive power of steel materials and metal membrane stably at application of way method of construction by normal temperature metal spraying. In case of metal spraying, Sticking strength of metal spraying way finish is influenced greatly, and it is judged that is desirable that manages Sm/Rz by 6 lows to secure more than sticking intensity 20kgf/cm(2) by Sm/Rz that evaluate that is rough of nature surface. The purpose of this study was to analyze an adhesion strength of metal spraying finish layer with the surface conditions of steel plate. For the purpose the experimental factors such as anticorrosive finish method and surface treatment method were selected.
