What is the surface treatment?
The surface treatment applies to any final procedure or a number of procedures that result in a change in the desired face properties produced items. Physical or chemical properties can be changed. Kovoworking, the textile and polymer industry often uses finishes to improve the properties and value of their products. Grinding, grinding, polishing and polishing are steps used gradually to increase smoothness. The smooth surface may be desirable for handling the material, tight mating of the machined parts or for aesthetic reasons. Reducing friction between the object and other material is a frequent reason for smooth surfaces. It can be measured directly by a contact profilometer, a device with a diamond pyramid of the stylus rides up and down the profile, after a programmed grid when the results are recorded. These devices measure RA from 0.1 to 0.4 microinches (3 to 10 nanometers). Non -contact profiles and interferometers measure RA with a wide range of optical measurements, which compares the angles at which with withE Light reflects and interference formulas. These machines can measure roughness in the range of 0.012 to 0.02 microinches (3 to 5 angstromes).
The surface properties of mirrors used in binoculars largely determine the quality of the images. Measurement of smoothness of these mirrors becomes as demanding as the surface treatment technique itself. The surface of the primary mirror Hubble Telescope has a total deviation of less than 0.04 microinches (10 angstromes).
Metal leaves or objects are often coated with polymers or paint to protect the pre -gorge and reasons. These finishes can be applied by spray or spraying or deposition of steam or powder. These methods can be achieved by the mirror finish. The last step may include curing, annealing or baking to adjust the surface and ensure adhesion on the base material. To adjust the surface of the finished object can also be usedembossed or etching.
Electropping is the practice of connecting the surface coating of one material into another by means of electrochemical methods. They are usually metals or metal alloys associated with other metal substrates. Hard, resistant to corrosion and attractive surface surface is a requirement for many components of cars, aircraft and boats. Similarly, medical components use electrical plants to achieve a surface that can be disinfected or sterilized.
In the textile industry, textiles can go through the surface treatment steps that add shine to the material, starch to help in handling or relief pattern. The material texture can be improved by brushing or scratching. Items made of polymers are often subjected to surface adjustments to change their texture, gas or liquid throughput or stiffness.
