Fine Particle Bombarding and its Use

In this day and age, automotive manufacturers are constantly looking for techniques to improve engine performance and efficiency. There are many aspects to it.

For example: Reducing friction between moving engine parts, increasing the metal's surface compression strength, and increasing the oil holding capability of a metal surface.

Keeping this in mind, I will discuss WPC or fine particle bombarding, which can provide all of this and more with a simple process.

WPC, or fine particle bombarding, is a well-kept secret when it comes to improving the performance of automotive engines. In high-performance sports like NASCAR and WRC, it is commonly employed.

WPC is becoming increasingly used to reduce metal friction and increase metal strength. So, what gives metal these properties? Let's find out what the procedure can do for us.

After browsing the Internet for hours, I learned about WPC and that the process has been kept a secret for nearly a decade. 

Many race car drivers and automotive specialists use this Japanese technique to this day. Let's take a closer look at what this is all about.

Fine particle bombarding or WPC is analogous to shot peening, which alters the metal surface's surface form, hardness, and lubricating oil retention qualities. 

It is possible to see surface irregularities with a naked eye with shot peening. Still, the medium in WPC (ceramic) is so thin that only a microscope can reveal them, meaning that the finish has about the same surface roughness as micro polishing.

WPC is a micro shot blasting treatment that forms tiny dimples on metal objects, minimising friction and boosting performance and longevity. 

Unlike a coating, fine particle bombarding, a permanent surface treatment decreases friction by reinforcing the metal parts. 

WPC finish on engine parts and other surfaces with friction spots is unequalled. Compressive stress is increased and brought closer to the surface using several shocks in the WPC process.

Also, WPC treatment does not impact essential clearances and tolerances by adding or removing material. At the points where the media is ejected at high speed to the product's surface, it causes compressive stress.

The ultra-fine substance used in WPC processing creates micro-grooves in the product's surface.

Once the WPC process is complete, no more case-hardening modifications are necessary for the hardened sections.

Metal surfaces are treated with WPC, which generates a nanocrystalline structure on their surface. Metal-to-metal contact is minimised by the WPC surface's micro-grooves, which also have a high lubricant retention capability.

The grooved surface also helps to reduce friction by reducing the overall contact area. Conventional surface treatment procedures cannot compete with the distinctive micro-pit pattern of WPC, which considerably lowers friction.

In a YouTube video by MotoIQ, WPC-treated metal parts are shown to have outstanding lubricity compared to regular polished parts, proving that WPC is a practical approach to increasing engine efficiency and lifetime.
