Engine and transmission

Our technology extends the life of both engine and transmission components

Surface coatings are used on engine valves, fasteners, fuel injector components, and gears. They improve factors including corrosion resistance, wear-resistance, and improve conductivity.

Additionally, when light metals are used our technology provides exceptional paint adhesion and resistance to galvanic corrosion. These factors help in meeting component service life and reducing fuel consumption.

Engine valves

Engine valve shafts are typically plated with 5 - 8 µm micro – cracked hard chromium to a hardness of more than 900 HV0.1. This coating delivers wear, and corrosion protection, as well as attaining low friction requirements. Combined, these benefits offer longer component life compared to untreated shafts.

Fasteners

Located under the hood and around the engine, powertrain fasteners need to provide excellent performance and durability. For example, corrosion resistance and friction requirements can vary across the engine and transmission systems – our extensive range of coatings can be tailored to fit these changing needs. ZinKlad 250 is recommended in this application as it offers the following benefits:

  • Exceptionally adherent coating
  • Heat resistant protective coating
  • Low film thickness with good abrasion resistance
  • Retains corrosion protection after manufacturing operations

 

ZinKlad is our exclusive quality system. With different performance levels and approved by automotive OEMs this methodology offers the following benefits:

  • OEM approved and certified coatings
  • Different levels of performance to match diverse requirements and specifications
  • Worldwide consistency; with a global network of approved applicators

Fuel injector components

Fuel injector components are typically Hardchrome plated within very tight thickness tolerances with an average of 5 - 8 µm chromium. This coating offers wear and corrosion protection, satisfying low friction requirements.

Gears

With higher standards for automotive components for reliability and service life, electroless nickel using boron-nitride technology is a great option. The coating achieves precise uniformity in parts of great complexity and difficult geometry. This combines with enhanced hardness for durability and excellent corrosion protection.
