WPC is a secret technique used to increase engine efficiency in automobiles. It is typically used in high-performance sports like NASCAR and WRC. 

The popularity of WPC continues to grow, and it is slowly becoming the most sought-after method to reduce friction and increase the strength of the metal. 

So, why is it so? Why is WPC so great, and what makes it so effective. Let’s find out and study the benefits of the process.

After researching the web for hours, I found out about WPC that the process has been a well-kept secret for almost a decade. This technique was developed in Japan, and race car drivers and automotive experts favour it. Let’s dive a little deeper into what it is.

WPC processing is similar to shot peening, which changes the surface shape, surface hardness, and lubricating oil retention properties of the metal surface. 

However, unlike shot peening, the medium used (ceramic, according to MotoIQ) is so thin that the irregularities in the surface are not visible to the naked eye and can only be observed with a microscope, where the finish has about the same surface roughness as micro polishing.

Thus, in a nutshell, WPC is a micro shot blasting treatment that produces micro dimples on metal parts that reduce friction and therefore increase performance and durability.  

The treatment is a micro dimple treatment process that improves the surface to reduce friction and increase the strength of parts. 

WPC is better because WPC is not a coating but a permanent surface treatment that reduces friction by strengthening the part.

The finish of WPC metal is unmatched on engine parts and other surfaces with friction points. Multiple shocks during the WPC process increase the compressive stress and bring it closer to the surface. 

WPC metal finishes do not add or remove material that could alter the critical clearances and tolerances of the part.

The media, which, when ejected at high speed to the surface of the product, creates compressive stress at the points of impact.

Fine grooves, which are inherently etched into the product’s surface during processing, are converted into micro-grooves by the action of the ultra-fine material during WPC processing. 

WPC allows hardened parts without noticeable dimensional changes, and no further case-hardening modifications are required once the process is complete.

WPC treatment creates a nanocrystalline structure on the surface of the metal. The micro-grooved WPC surface helps maintain an oil film that reduces metal-to-metal contact. 

Also, the grooved surface helps to reduce the contact area overall to reduce friction. The unique micro-pit pattern of WPC significantly reduces friction and is unmatched by conventional surface treatment methods.
