Moving One Step Further than Shot Peening

Shot peening is an essential mechanical process used in a wide range of fields. Shot peening is based on the same idea that blacksmiths used to use when they hammered metal repeatedly to make it stronger.
Shot peening makes metal last longer before it wears out, and it's the best way to get hardened results. This is done to change the metal in a way that doesn't use heat.
Shot peening is a process where small shots are used to make changes in the surface of the metal.
This process will make the metal last longer in the long run, which is important when making important machines like cars and planes.
With shot peening, small spheres are shot at the surface of the metal from different nozzles.
In 1982, NASA did several tests that showed that shot peening increases metal hardness.
These tests were a turning point in the field. After this happened, shot peening was used a lot in the auto industry.
Because it makes things harder, automakers started to use it more and more for gears in cars and trucks. This study changed the way cars are made because it made shot peening a standard part of the process.
Shot peening does not take anything away. This process makes tiny holes in the thin layer of material on the surface. As was already said, this process makes the object stronger and lasts longer.
The material becomes much stronger by giving the item these tiny changes and causing the metal to compress. Nothing is taken away or added to the metal during the shot peening process.
So, shot peening seems like a great idea. Yes, it does. But what if I tell you there is an even more advanced method to improve the durability and lubricity of automotive engine parts.
I am talking about WPC or the process, where ceramic spheres are fired on the metal surface; however, the balls are almost microscopic, and the velocity at which they are bombarded is much higher than shot peening.
WPC is being used extensively in engine parts for WRC, NASCAR, MotoGP, and other competitive motorsports worldwide and continues to gain popularity.
Since the blasted media is very small, it is not visible to the naked eye but gives the metal surface higher compressive strength. Also, the media is laced with solid lubricants that improve the lubrication of the surface, even when no oils are used.
Furthermore, the micro pits formed on the metal surface hold lubricants well and further reduce friction.
Many case studies have proven that WPC or fine shot peening can reduce costs by reducing engine wear, maintenance costs, and improving fuel efficiency. The motorsport world is excited about WPC; however, you can use it on high-performing streetcars.
