Engineered Components

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.

Tribobond^™  coatings provide performance enhancement for virtually any type of industrial pump. Among the most common applications are:

• Compression rods/pistons of plunger/piston pumps
• Gears, shafts and housings of gearwheel (rotary gear) pumps
• Vanes of rotary vane pumps
• Components of single- and multistage centrifugal pumps
• Lobe pump rotors

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.

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.

Examples of applications include:

• Balls, seats, packing and stems of ball valves
• Sealing surfaces of needle valves
• Gates and stems of gate valves

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.

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.

Examples of applications are:

• Collet chucks
• Elements of high-speed spindles
• Elements of linear drives
• Probe elements of metrological tools

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.

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.
