high temperature laser cutting Alumina Ceramic gear spacer
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
The oxide film of the anodized aluminum plate is generally above 12μ, the color is only bronze and white, and the color is monotonous. The more serious disadvantage is that the color of each aluminum veneer board is different, and many pieces of curtain wall panels are combined to form one. The overall effect of the curtain wall is very ugly. Generally it can only be used for interior decoration and is not easily accessible to people. The anodized aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, in the specific Under the condition and the applied current, the electrolysis is performed. The aluminum plate of the anode is oxidized, and a thin layer of alumina is formed on the surface, the thickness of which is 5-20 micrometers, and the hard anodized film can reach 60-200 micrometers. In the solution, the process of forming an aluminum oxide film on the surface by electrolysis is called anodizing treatment of the aluminum plate. The cathode in the device is a material with high chemical stability in the electrolytic solution, such as lead, stainless steel, aluminum, etc. The principle of anodizing is essentially the principle of water electrolysis. When the current passes, hydrogen is evolved on the cathode; on the anode, the oxygen evolved is not only molecular oxygen, but also atomic oxygen (O) and Oxygen, molecular oxygen is usually expressed in the reaction as the aluminum is oxidized anode deposited thereon oxygen, water-free aluminum oxide film is formed, not all of the oxygen produced aluminum effect, a portion of the gaseous form of precipitates.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
