What is the surface integrity?
surface integrity reflects the properties of the material after it has been subjected to a certain type of production process or treatment. Product engineers and product designers often plan projects based on known characteristics of a particular metal. For example, these designers know that a particular steel alloy offers a set level of force or hardness. After modifying the material, these original properties may no longer apply, as many production processes create a permanent change in material. Surface integrity helps these individuals to determine how the material changes under certain conditions and what the new features are compared with its old ones.
The surface integrity of any material consists of two basic ingredients. They include topography and internal surface features of the product. Topography reflects changes on the outer surface of the material and includes things such as smoothness, bumps or wool, drinking and cracks. Address of internal functions just below the outer surface, such as deformation and change of strength or hardness. Do not include innerChanges deep in the heart of the material, but rather in a layer just below the surface.
Finally, most production processes will have a certain impact on the integrity of the surface, although it may not always be. Standard lathe, grinding or milling, when done correctly, does not affect the integrity of the surface. If these processes are carried out using poor techniques or boring tools, they can have a great impact on material properties. Excessive heat, colds or speed or work can also lead to significant changes.
More invasive procedures almost always have some permanent effect on surface integrity. They may include electrical treatment such as plating, which adds a permanent coating to metal or chemical treatment. Almost any chemical treatment, as excessive heat, can change the material to the molecular level and bring irreversible changes in its structure. Repeat and other types of deformation also bring fromCurrency, especially when applying to plastics.
Surface integrity changes can be positive or negative. Negative changes could mean that the material can no longer be used according to the intended. For example, a steel column subject to extinguishing may eventually be too fragile to support the structure. Positive changes are those that provide the material desired or appearance such as burning to smooth a rough piece of material. Positive changes in surface integrity also include those that improve properties such as hardness, strength or moisture resistance.
