Surface treatment methods of stainless steel materials

Surface treatment method of stainless steel materials:

Dalian metal surface treatment, the axis of the robot is commonly known as the joint, like a human arm. Of course, the more joints, the more flexible, and more positions can be rotated and reached. Moreover, the more the number of robot axes is, the more complex the robot control system is, the higher the cost is, and the more points can be reached in three-dimensional space, which is relatively flexible. However, with the increase of the number of axes, the stiffness of the robot decreases, the inertia increases, the dynamic performance decreases, and the load and motion speed decrease.

 

At the same time, the control difficulty of the robot is greatly increased, and the solution of the inverse solution will be difficult, which increases the requirements for software algorithms and hardware. When the spur gear is engaged, the whole tooth enters at the same time, and there is "positive stiffness" between the teeth, which will produce a strong impact force, and the vibration will be obvious. Helical gear is characterized by stable transmission, strong bearing capacity, less noise and impact, and is suitable for high-speed, high-power gear transmission. Material surface treatment plays an important role in beautifying the appearance and improving the service life of automobile parts.

At present, common material surface treatment technologies include electroplating, chemical plating, vacuum degree, coating, alloy catalytic solution, etc. Comparatively speaking, alloy catalytic liquid is more popular in automobile industry as a new surface treatment technology of environment-friendly materials. The occurrence of elevator accidents is caused by many factors, including improper operation of passengers, long service life of the elevator, and failure to timely repair the elevator. However, the occurrence of elevator accidents is closely related to the material and quality of its parts. On the one hand, some businesses produce unqualified parts driven by interests, and on the other hand, the surface treatment of metal parts is not in place.

Stainless steel materials have good rigidity, processing formability and corrosion resistance, and are widely used. However, after repeated use, cleaning and disinfection of stainless steel products, the surface coating will be worn and easy to breed Escherichia coli, Staphylococcus aureus and other bacteria, which will lead to infectious diseases. The glass sand is sprayed by using compressed air as the power to form a high-speed jet beam to spray the glass beads onto the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the external surface of the workpiece surface changes, which can remove the tensile stress of various parts, increase the fatigue life and improve the stress resistance and corrosion resistance.

Long term production practice has proved that if there is oil stain and other organic substances on the metal surface, although sometimes the coating can also be deposited, the flatness, adhesion and corrosion resistance of the electrodeposited coating are always affected by the oil stain "interlayer", even the deposition is discontinuous, loose, or even the coating is peeled off, making it lose its practical use value. Therefore, degreasing before plating becomes an important process operation.
