Increase lifetime, improve operating efficiency and reliability of various engineered components
Coatings for mechanical components
Many mechanical components in industrial machinery have to operate under adverse conditions, for example high loads, aggressive environments, lack of lubrication or the presence of abrasive particulate. In addition, there are high demands on maintenance-free durability and operational cost savings.

Engineered components coating applications
Tribobond™ coatings are designed to meet the challenges that mechanical components are exposed to. They extend the lifetime of components, which is a strong contributing factor to sustainability, and often become an enabling element without which operation is not possible.
Compressors
Tribobond™ coatings are applied to components of various compressors to improve wear performance. Coating the vanes of refrigeration compressors makes them less dependent on lubrication and therefore friendlier for CFC-free operations. Coating the rotors of screw compressors allows more reliable operation in dry conditions and provides additional corrosion protection. Even common piston compressors benefit from heavy-duty Tribobond™ films.
Pumps
Tribobond™ coatings provide performance enhancement for virtually any type of industrial pump. In addition to the moving components of the pumps, elements such as mechanical shafts seals are also regularly coated with Tribobond™ coatings. These seals can be made out of steel, cemented or silicon carbides.
Valves
In many industries, including oil and gas, food and the chemical and pharmaceutical industries, coatings on valves help combat abrasive wear, prevent seizing and galling, decrease actuation forces and provide lubricant-free operation. Tribobond™ and Ionbond™CVD coatings are successfully implemented in many of these industries to protect valves of various types.
Bearings
Rolling contacts in bearings and gears are typically subjest to high contact loads. Certain coatings in the Tribobond™ family are specifically designed to help reduce rolling contact fatigue, one of the failure modes in such contacts. Specialty Tribobond™ films help minimize the adverse effects of contact fatigue and increase the load-carrying capacity. In addition, these films decrease friction in poor lubrication conditions, thus increasing transmission efficiency.
Hydraulics
Pistons, piston rings and piston rods of hydraulic and pneumatic actuators are subject to high wear and are usually protected with hard chrome plating or sprayed coatings. Tribobond™ coatings are a powerful alternative to these technologies. The environmental limitations of chrome plating is forcing manufacturers to look for alternatives. For this application, sprayed coatings are often not cost effective, since the parts require grinding after processing. Tribobond™ coatings do not require post-finishing and are environmentally neutral, making them an ideal solution for hydraulic and pneumatic actuators.
Tribobond™ coatings are also widely used to treat components of hydraulic motors, pumps and transformers. These coatings shine in heavy-duty devices with high loads and low rotational speeds, when efficient lubrication is difficult.
Collet chucks
Long-term dimensional stability is critical for precision machine and metrological tools. With their high hardness and negligent wear rate, Tribobond™ coatings are widely applied to maintain the accuracy and longevity of machine tools and related accessories.
Locating pins
Modern manufacturing often relies on automated robot-assisted assembly operations that run with virtually no interruptions. That means long-term reliable operation of every single element of the assembly line is crucial. Tribobond™ coatings help provide the wear reduction and lifetime increase of mechanical assembly line elements that make this type of operation possible.
Among such components are locating pins that help fix sheet metal components for welding. Frequent insertion of these pins in openings in the sheet metal leads to wear and some adhesive effects. Failure of these locating pins may lead to expensive stoppage of an assembly line. Tribobond™ coatings help prevent both wear and galling issues on such pins, substantially extending their life.
Welding pins
A similar application are resistance welding pins. In addition to wear properties, these pins must be electrically insulating to enable the correct path of the welding current. Application of Tribobond™ or Bernex™ coatings increases the lifespan of these pins by several times, while providing the necessary electrical properties.
Textile
Protection against premature abrasive wear is critical in virtually all stages of textile manufacturing, including spinning, weaving and knitting. Both cotton and synthetic threads can be highly abrasive to elements of textile machinery. With stricter environmental regulations being enacted, replacing hard chrome plating, which common in the industry, is becoming an important issue. Tribobond™ and Ionbond™ CVD coatings offer an environmentally friendly and effective protection against wear of key textile consumable components.
Ceramics manufacture
Extending the lifetime of extrusion dies, such as those used for manufacture of fine-walled ceramic inserts of catalytic converters and diesel/gasoline particulate filters, offers immediate commercial benefits for users. Specialty Ionbond™ CVD coatings protect the inner channels of these very expensive tools. With proper die management, multiple recoating cycles are possible, thus further extending the life of the die.
