Abstract
A composite comprises nylon and a ceramic material. The composite may be used to coat hydraulic cylinders. The coating process typically comprises a thermal spray method, whereby an induction heater may be used to control the substrate temperature at 70°C. The ceramic material may be white alumina, chrome oxide, or alumina titania. The nylon may be white nylon, gray nylon or black nylon. The coating is intended to be hard wearing and have a high chemical resistance.
Description
Composite Coating of Ceramic and Polymer For Hydraulic Cylinders The present invention is a Ceramic Nylon composite.
This is a realistic alternative to hard Chrome Plating, suitable for the harshest marine environment. The Hydraulic Cylinders are coated with a combination of Ceramic and Nylon. The composite has a low coefficient, outstanding durability along with unique corrosion protection. It has extremely hard wearing properties whilst retaining a high chemical resistance.
Custom made powders have been developed to create a hard wearing coating. The combination of Ceramic particles are fused within a matrix of Polymer which then blends together producing a corrosion resistant Cylinder.
The Cylinder is turned to 1mm below the finished outside diameter and then grit blasted to produce a clean rough finish in order to produce a good bond strength.
Prior to applying an initial Thermoplastic bond coat, the Cylinder needs to be preheated to 70C and maintained throughout the coating process. An induction heater provides close temperature control whilst the induction ring is traversed simultaneously along side the thermal spray gun. Other forms of preheating may also be used.
This Thermoplastic bond coat is used because it adheres to the substrate and requires little preheating whilst improving the corrosion resistance.
The thermal spray equipment to produce the initial bond coat requires propylene, oxygen and compressed air. The Cylinder is rotated and traversed then a single pass of Thermoplastic is delivered through a powder feed hose.
To produce the top coat the propylene gas is replaced by acetylene and the composite powder is introduced into the hopper. This produces a hotter flame suitable for the Ceramic/Nylon composite.
Different Ceramic materials may be used and need to be matched with the appropriate colour of Nylon. White Alumina is mixed with white Nylon, Chrome Oxide, with black Nylon and Alumina Titania, with gray Nylon. The percentage of Ceramic to Nylon may be varied to suit the application.
Once coated the Cylinder requires diamond grinding and then super finishing. The finish required is between 0.2 to 0.8 C.L.A. This can be achieved by the use of specially designed diamond belts and diamond lapping film, along with silicon carbide polishing film.
Claims (5)
- CLAIMS1. The present invention is a Ceramic Nylon composite.This is a realistic alternative to hard chrome plating, suitable for the harshest marine environment, the Hydraulic Cylinders are coated with a combination of Ceramic and Nylon. The composite has a low co-efficient, outstanding durability along with unique corrosion protection.It has extremely hard wearing properties whilst retaining a high chemical resistance.
- 2. The product is unique because it uses a thermal spray process and an induction heater controlling the substrate temperature at 70C.
- 3. The cylinder requires a Thermoplastic bond coat using propylene, oxygen and compressed air. As the substrate requires little preheating it saves on time and energy, producing less stress in the Cylinder whilst improving corrosion resistance.
- 4. The top coat is a composite powder produced using acetylene, oxygen and compressed air providing a hard wearing cylinder.
- 5. Different ceramic materials may be used and need to be matched with the appropriate colour of Nylon. White Alumina is mixed with white Nylon, Chrome Oxide with black Nylon and Alumina Titania with gray Nylon. The percentage of Ceramic to Nylon may be varied to suit the application.
