Solution & Advantage 

Over past 30 years, PVD ion plating is one of the most rapidly developing surface treatment technologies. PVD ion coatings with film thickness form 1 to 100 μm can improve the wear resistance, corrosion resistance, high temperature oxidation resistance and lubrication performance, and it has been extensively applied on aerospace and ordnance industries. Recently the aerospace industry increasingly concerns in reducing carbon emissions, maintenance costs and total operating costs, and in turn emphasizing on weight reduction, longer life, and fuel consumption reduction, the PVD coatings on those parts can play vital important roles to enhance their overall performances. Different from conventional surface treatments, PVD is an environmentally friendly green technology without any pollution problems.
 
Tolerant to more harsh environments
 
On metallic parts, coatings can help to extend parts’ service life and achieve higher benefits.
Coatings are usually applied to increase parts’ features, such as to provide thermal barrier or heat transfer under various load and temperature conditions and so on: 
Typical areas of application include engine and mechanical parts, bearing and actuator.
 
  ● Reduce friction, wear, corrosion and abrasion
  ● High temperature hot corrosion
  ● Chemical inertness 
 
Longer service life
 
Many parts in aviation industry will expose towards dust and dirt and subjected to various mechanical brushing and thermal shocks. 
ProChina’s coating technology can reduce wear speed and extend service life of key parts and in turn the entire equipment, as well as prolong maintain cycles, reduce operational costs, lower spare parts inventory, and shorten maintenance time and complexity, so as to optimize costs and minimize the impact on environment.
 
  ● Increase surface hardness
  ● Self-lubrication function
  ● Low-wear characteristic
 
Diffusion films on turbine blade
 
As the hottest components on a jet engine, turbine blade will usually expose to extremely harsh environments. Even inside cold air-tunnel, the blades made of super-alloys might be still failure due to hot corrosion. 
ProChina’s relevant solutions provide effective protection for the above critical parts. Contrary to conventional wrapping, PVD coated diffusion type aluminum-based films with uniform thickness and self-healing feature, can extend service life of turbine blades.
As well as composite base films or alloy films on customer special requirements.
 
  ● Able to operate under even higher working temperature
  ● Increase fuel efficiency
  ● Reduce hot corrosion
