Anti-wearing
APT thermal spray coating applied for anti-wearing !
In the industrial process, wear is ubiquitous, which can shorten the life of some components and cause high maintenance costs. APT thermal spraying coating contributes to wear resistance. Based on the most basic principle, our engineers find and determine the wear mechanism existing on the equipment or parts, so as to prolong the service life of the alloy or coating, metal, polymer, ceramic or their mixture.

- Abrasive wear
- Surface fatigue
- Fretting wear

Wearing Description
Adhesive wear
When the friction pair moves relative, due to the solid phase welding, the material on the contact surface transfers from one surface to another, which is called adhesive wear.
Abrasive wear
There are hard particles or hard protrusions between the friction surfaces (such as dust, wear debris, hard spots in the material structure, sand inclusion in the casting, etc.), in the process of friction, abrasive wear occurs on the metal surface such as abrasive wear
Surface fatigue
When two contact surfaces are in rolling or rolling sliding composite friction, under the action of alternating contact pressure stress, the material surface is fatigued and the material loss is called surface fatigue wear.
Fretting wear
There is no macro relative movement between the two contact surfaces, but there is a small amplitude of relative vibration (less than 100 μ m) under the influence of external variable load. At this time, a large amount of micro oxide wear powder is produced between the contact surfaces, so the wear caused is called fretting wear
Erosive wear
In the process of friction, the surface metal reacts with the surrounding media in chemical or electrochemical way, resulting in material loss
Corrosion and oxidation wear
In the process of friction, the metal and the surrounding media have chemical or electrochemical reaction, resulting in material loss, which is called corrosion wear
