  • Metal surface treatment during coating

    2022-12-30
    3、 Treatment before metal coating (1) structural treatment of sharp corners, splashes, welding slag, welding holes, etc., chamfering treatment to reduce stress concentration, etc. (2) The surface shall be cleaned of oxide scale (rolling), rust, soluble salt, grease, insoluble solids, moisture (excluding water-based paint), etc. (3) The surface roughness improves the roughness and increases the mechanical engagement between the coating and the substrate. If the roughness is too large, the convex part may cause the local coating to be too thin, and the residual bubbles in the pits will lead to premature failure of the coating. Generally, the roughness should be 1/10 of the coating thickness.

    2022-12-30
    For metal surface coated castings, the surface treatment methods we commonly use include mechanical polishing, chemical treatment, surface heat treatment, spraying surface, etc. The surface treatment is to clean, clean, deburr, remove oil stain, and scale the workpiece surface. The surface treatment of metal is also particularly important in the coating process, which is related to the quality and effect of spraying.
  • Development trend and direction of metal surface treatment in dalian

    2022-11-07
    Dalian metal surface treatment technology is a broad and profound basic technology with practical value, as well as a new frontier discipline. Surface technology originated in ancient times, but only since entering this century, with the extensive research on natural phenomena and the rapid development of industry and science and technology, a series of improvements, combinations and innovations have been made to traditional surface technology, and a large number of modern surface technologies have emerged.
  • Difference between traditional surface treatment technology and modern treatment technology

    The difference between traditional surface treatment technology and modern treatment technology:
  • Common metal surface treatment process

    Common metal surface treatment processes:
    The surface of metal materials generally solves the technical problems. This paper introduces the surface treatment of stainless steel plate, aluminum alloy, die-casting aluminum, zinc alloy materials and other metal materials in detail: Dalian metal surface treatment
  • Surface treatment methods of stainless steel materials

    2022-10-28
    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.
