Hardness indicates a material's ability to resist hard objects being pressed into its surface. It is one of the important performance indexes of metal materials. Generally, the higher the hardness, the better the wear resistance.The hardness of Vickers (HV) is obtained by dividing the load value by the surface area of the indentation pits of the material by the diamond square cone impinger with a maximum load of 120kg and a top Angle of 136°.
