IRS Keeping History on the Road

At IRS it’s not just about supporting industry but also helping the individual.

An inquiry came in from Phil asking us if it was at all possible to reclaim the axle bearing location diameter on his 1960 Hotchkiss M201, no problem!!

A a little bit of history for you all!! The Hotchkiss M201 was the standard light transport vehicle used by the French army from shortly after the war until it began retiring them from the French service in the 1980s. It started as a World War II jeep built under license and in many respects was a little changed forty years later.

In France it is usually simply called ‘La Jeep”.

What is Flame Spraying?

flame spraying imageFlame spraying is a thermal spray process that creates quality coatings using heat to melt materials that are usually in powder, ceramic rod or wire form. This type of thermal spray method is cost effective and one of the simplest ways to deposit coatings onto a substrate to provide impact resistance and protection from wear and tear.

How does Flame Spraying work?

The flame spraying process is fueled by a heat source that is created by a chemical reaction between a fuel of combustion and oxygen to create a stream of gas. The thermal spray material is then put into the flame in the form of a wire and compressed air is used to atomise the molten particles before propelling them onto the substrate. If you use a powder flame spray, the powder particles are softened by the flame before they are coated by the flame gases and accelerated through the nozzle.

What is Flame Spraying used for?

Widely used as a cost effective method of protecting components and structures from damage and corrosion, flame spraying is used on a variety of different substrates. When equipment or a structure is required to have a high resistance, flame spraying is used to apply metallic and ceramic coatings so they are suitable for the environment they are being used in.

What are the advantages of Flame Spraying?

Cost effective

Flame spraying will is not as costly as many other forms of spraying due to the nature of the process and the finished quality of the coating.

Lower dust and fume levels

With lower dust and fume levels than plasma and HVOF spraying, flame spraying can be used without a spray booth and also has lower noise levels.

Coat complex geometry

Due to the nature of manual flame spraying, it is easier to coat equipment and components with complex geometry.

Portable and easy to use

Compared to other thermal spray processes, flame spraying is made from a more simple design making it easier to use and it is suitable for manual use without the need for mechanised manipulators.

What are the disadvantages of Flame Spraying?

Lower-quality coatings

The coatings achieved by flame spraying are of a lower quality than those by other thermal spraying processes, however this is fine for environments which are less demanding. The coatings may have higher oxide levels for metal deposits, higher porosity and a lower bond strength.

Difficult to coat restricted surfaces

Like most thermal spraying processes, flame spraying requires line of sight to the surface to coat. This means it is difficult to coat restructured surface areas or inner surfaces with a smaller diameter.

If you would like to find out more about flame spraying or the other quality coatings we provide for you and your business operations, please don’t hesitate to get in touch. Here at IRS, we are fully committed to providing durability and high performance through our range of applications.

What is Precision Grinding?

Precision grinding is a precise manufacturing process used across a diverse range of sectors, Precision Grindingproviding an efficient way to complete the fabrication and finishing of metal parts with very close and tight tolerances.

There are a number of different precision grinding techniques that can be adopted in order to achieve desired affects including cylindrical grinding and surface grinding. And, although this process is mostly carried out in factories, many companies are also happy to perform precision grinding off site too for added convenience.

These processes use a specialist spinning wheel that has been made of bonded abrasive particles in order to successfully remove a vast range of materials from the object that is being re-surfaced. The technique, which is right for the part that you are working on, will depend on its individual specification requirements.

With this in mind, it is also crucial that the technician also uses the correct tools in order to optimise results at every stage of the process. This is because there are a number of different tools that should be used based on the shape, size and texture of the part being worked on.

What type of parts requires precision grinding?

It’s mostly tiny metal parts such as the components found in many modern electronic devices that require precision grinding.

However, there are also a number of larger parts that also require precision grinding and these include parts that are commonly used within aerospace instruments, medical devices, bladed implements, as well as a number of different scientific instruments.

The majority of precision grinding projects can be adapted to accommodate the exact specification of a wide range of different parts.

Of course, there are also a number alternatives to precision grinding, which can also be used to accommodate the needs of the applications mentioned above however, these tend not to be as cost effective or precise.
