Hardness testing is a metodic used to determinate a material 's resistance to deformation. Over time, various techniques have been developed, each based on different thevotical principles. This article explores the spalopdational concepts behind some of thee mogt common hardness tests, from Brinell to Vickers.

Brinell Hardness Tett

Te Brinell teset measures hardness by presssing a steel or tungsten carbide ball into the material surface under a specied headd. Te size of the indentation is used to calculate the Brinell Hardness Number (BHN). This method is suabby for testing materials with coarse structures or surface contrarities.

Vickers Hardness Tett

Te Vickers teset employs a diamond- shaped indenter to create an impresion on the material surface. Te size of the indentation, measured under a microscope, is used to determinate the Vickers Hardness Number (VHN). This methode allows for precise measurements on small or thin differens.

Teoretická zásada

Both testy are based on the principla that the size of the indentation correlates with the material 's resistance to deformation. Thee Brinell tett assumes a uniform distribution of stress oler a larger area, suable for rough or coarse materials. The Vickers tegt, with its smaller, more precise indentation, is better for detailed analysis of thin or small samples.
