Introduction
In today’s industrial landscape, where machines are subjected to intense operational stress, high temperatures, friction, and corrosive environments, maintaining the integrity of components is more critical than ever. Unexpected breakdowns can lead to costly downtime and reduced productivity, especially in industries such as oil and gas, marine, energy, and heavy manufacturing. To combat these challenges, WWG Engineering offers comprehensive thermal spray coating services that enhance the performance, longevity, and reliability of mechanical parts and surfaces.

Specializing in advanced technologies like Flame Spray Coating, Wire Spray Coating, and Rokide Coatings, WWG Engineering is committed to delivering high-quality, customizable solutions tailored to the specific needs of each client. Combined with top-tier thermal spray equipment and a wide range of consumables, WWG is not just a service provider but a full-fledged solutions partner.

Flame Spray Coating: A Cost Effective Surface Solution
Flame spray coating is one of the most accessible and widely used thermal spray processes, known ...
... for its versatility and affordability. The technique involves melting a metal or alloy in a controlled flame and spraying it onto the surface of a component. The resulting coating forms a rough but adherent layer that protects against abrasion, corrosion, and chemical attack.

One of the primary advantages of this method is that it does not significantly heat the substrate, making it suitable for coating temperature sensitive materials. Flame spray coatings are frequently applied to agricultural machinery, pipelines, pump impellers, and industrial rollers. These coatings can be used both for rebuilding worn parts and for preventive surface treatment.

The method is especially beneficial for onsite repair jobs, where mobility and cost-efficiency are crucial. Due to the relatively low equipment cost and operational simplicity, flame spray technology is a go to choice for many companies seeking reliable surface protection without the expense of more sophisticated systems.

Wire Spray Coating: Uniform and Durable Protection
Wire spray coating offers improved coating quality, density, and mechanical strength. In this process, a wire made of the desired coating material is fed into a gun where it is melted, atomized, and projected onto the surface using compressed air. The result is a high-performance coating that offers superior bonding and uniform coverage.

This technique is widely used in demanding industries such as aerospace, defence, and automotive, where components must endure continuous stress, vibration, and high-speed motion. Applications include crankshafts, brake rotors, turbine blades, and hydraulic piston rods. The even thickness and minimal porosity of the wire-sprayed coatings contribute to long-term durability and consistent performance.

Additionally, the flexibility to use a wide variety of wire materials, such as stainless steel, aluminium, bronze, and nickel alloys means wire spray can be tailored to specific functional requirements, including electrical conductivity, heat resistance, and chemical protection. WWG Engineering uses state-of-the-art thermal spray guns to ensure consistent spray patterns and optimized results for each project.

Rokide Coating: Premium Ceramic Armor for Extreme Conditions
When maximum protection is required, Rokide coatings offer an unmatched level of performance. Unlike traditional flame or wire spraying, the Rokide process uses dense ceramic rods like Rokide c that are transformed into ultra-durable crystalline coatings upon impact. These coatings exhibit exceptional resistance to wear, oxidation, thermal shock, and chemical exposure.

Rokide coatings are often applied in power plants, petrochemical refineries, and high-temperature processing units. They protect components such as furnace tubes, nozzles, rolls, and plungers that operate in extremely harsh environments. The ceramic nature of these coatings makes them ideal for reducing friction and minimizing surface degradation, even in the presence of abrasive particles or corrosive agents.

Because the coating material is accelerated to high speeds and maintains its structural integrity upon deposition, Rokide coatings have a smoother finish and greater hardness than most other spray methods. They also exhibit low porosity, which reduces the risk of moisture or chemical ingress, thus offering longer protection cycles.
