An Investigation Into the Effects of the Hot-Dip Galvanization Process on the Mechanical Performance Characteristics of Steel Bolts
To study the effect of hot-dip galvanization process on the mechanical properties of steel bolts.The mechanical properties of hot-dip galvanization layer on the surface of steel bolts were analyzed and evaluated through hardness testing,twist off wear resistance,tensile strength testing,and microanalysis.The results showed that the microstructure and chemical composition of steel materials didn't change,and the tensile strength of treated bolts met the standard requirements after hot-dip galvanization process treatment,indicating that the hot-dip galvanization process had little effect on the mechanical strength of bolts.However,the hot-dip galvanization process can significantly improve the twist off wear resistance and microhardness of steel bolts,which provides a solution for large-scale use of hot-dip galvanization process for steel bolts.
