Surface Treatment (Technology)

Brushed

Types of metal surface drawing

1. Straight grain drawing on the metal surface refers to the straight-line texture processed by mechanical friction on the surface of the metal plate. It has the dual function of brushing scratches on metal surfaces and decorating metal surfaces. There are two types of straight line drawing: continuous silk pattern and intermittent silk pattern. Continuous […]

PVD

Why should PVD be performed in a vacuum environment?

PVD (Physical Vapor Deposition) refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target material and ionize the evaporated material and gas, and utilizes the acceleration of the electric field The evaporated substance and its reaction products are deposited on the workpiece. 1.  Prevent gas

Electrophoretic paint

What is electrophoresis Electrophoresis is the abbreviation of electrophoresis phenomenon, which refers to the phenomenon of charged particles moving towards electrodes with opposite electrical properties under the action of electric field. Under the action of an external DC power supply, the colloidal particles move directionally towards the cathode or anode in the dispersed medium. This

Oxidation coloring of aluminum die castings

The processing of aluminum die-casting parts adopts artificial methods to form an oxide film on the surface of aluminum and its alloy products and apply different colors to improve the wear resistance of aluminum materials, prolong the service life and increase the appearance of color and luster. The basic process of oxidative coloring is aluminum

hard oxidation coloring treatment

Three points to pay attention to in hard anodized coloring

Products made of aluminum products have many advantages. First, the production process is extruded and the production process is relatively simple. Second, aluminum production is not easy to rust and the product is durable. Therefore, there are relatively many designs of aluminum products at present. Then in the surface treatment, the aluminum products should also

Aluminum-anodizing

Introduction to the knowledge about anodizing of surface treatment

An oxide film with a thickness of 3-30um is formed on the surface of aluminum or aluminum alloy by artificial methods, so as to improve the corrosion resistance, wear resistance, ability of adsorbing paint and pigment, hardness and insulating properties of aluminum and its alloys. The basic reason: the anodization of aluminum is essentially the

Aluminum anodizing

What is the difference between anodizing and electroplating

Anodizing is a method of metal surface treatment. As an anode metal material, forming a thin film on its surface by an applied current in a specific electrolyte is a material protection technology. Most metal materials (such as stainless steel, zinc alloys, aluminum alloys, magnesium alloys, copper alloys, titanium alloys) can be anodized in a

sandblasting-oxidation

What are the main uses of sandblasting oxidation

It can remove dirt such as rust from the surface of the workpiece and form a very important basic pattern on the surface of the workpiece (the so-called rough surface). In addition, by changing the abrasives of different sizes, different roughness can be achieved, which greatly improves the bonding force between the workpiece and the

aluminum-oxide

What are the defects of aluminum oxidation processing?

Anodizing of aluminum and aluminum alloys is superior to chemical oxidation and can be used as the basis for final corrosion protection, decoration or coloring, dyeing and electrocoating. According to the type of electrolyte and film performance, anodizing can be divided into sulfuric acid method, chromic acid method, oxalic acid method, mixed acid method, hard and
