Coatings

When specifying Sherardized components, it is vital to consider the factors specific to the process itself

Top Coatings Post Sherardize

Sherardizing as a standalone system is a long lasting and cost efficient method of providing corrosion protection. The application of additional coatings produces a protective system with enhanced protection and performance. The resulting system may sometimes be known as a duplex system.

Sherardize / Shera-seal (Xylan Fluoroploymers)

Fluoropolymer coatings are a blend of high performance resins and lubricants which provide excellent corrosion and chemical resistance, reduced friction, electrical resistance and abrasion resistance.

Sherardized/Molybdenum Disulphide Duplex System Sherardize Md40®

Molybdenum Disulphide coatings are commonly used in applications where load carrying capacity, operating temperature and coeficient of friction are primary concerns. Moly coatings lubricate sacrificially by transferring lubricant between the two surfaces, helping to reduce wear and friction.

Sherardized/Phosphate/Oil Duplex System

Phosphate and oil coatings are often used to enhance corrosion protection, lubricity and to help prevent galling (surface damage)Phosphate alone serves as a conversion coating, providing a key for subsequent coatings.

Benefits of a Sherardized Duplex Coating

Barrier Protection – Alternatives to Sherardizing

Sherardizing is an extremely effective corrosion protection solution, however there are applications where other technologies may be appropriate.

 

As leaders in anti-corrosion technologies, Sherardize UK offer an extensive range of coating systems which can be used on their own or in conjunction with sherardizing as a Duplex Coating.

Sherardize Uk Coating Services Include:

Zinc Phosphate Passivation

Passivation is the removal of surface contaminants produced by machining and fabrication. The contaminants are potential corrosion sites which ultimately result in the deterioration of a component if not removed. Xylan® Fluoropolymers (Sherarseal).

Fluoropolymers are probably best known as non-stick cookware coatings, however, they are now a critical component in aerospace, electronics, telecoms, automotive and defence industries.

Amongst other properties, fluoropolymers can offer significant corrosion protection.

Molybdenum Disulphide Dry Film Lubrication

A durable bonded coating containing a blend of Molybdenum Disulphide(MoS₂) and thermosetting resin binder provides improved lubrication and corrosion protection in aggressive environments.
