We have taken up in this study the negative effect of the secular change where the phosphate treatment is applied in the frictional surface treatment of the hot dip galvanizined friction joints. We have carried out a relaxation test of the friction joints and slip test thereof after exposure as a method of investigation. As a result of it, it has turned out that the phosphate treatment shows the higher performance with relaxation less than the blast treatment and without any major negative effect during the slip test after exposure. therefore, we wish to make a report of it here.
