Friction is the force that pushes against anything that moves across another object. When we walk, we’re able to do effectively because there is friction the soles of our feet. This friction is not present in areas like ice rings and hence people will find it difficult to walk along those surfaces. Another thing friction is known for is its tendency to produce heat. If you were falling down a cliff but there was a rope tied next to a rock and it ran the length of that very cliff, trying to grab hold if and slow your descent will produce incredible friction your bare hands.
This friction will be enough to burn your skin and rip it apart and it will be painful making it near impossible to be able to hold onto the rope for very long. And just like how we humans experience friction, so does every thing else. Most notably is the heavy machinery that run in the industrial sector. Any certain system will have gears turning against each other producing vital outcomes at regular intervals but as these small bits and pieces push and pull against each other, they are affected by friction.
Sometimes, we don’t want that friction to be around. It makes inserting or removing certain technical parts of the system difficult and that’s an added strain we don’t want to have. Just like how there are coatings available to reduce corrosion as well as be able to stand high temperatures, there are also hydrophilic coating which can be used to provide a low friction environment to whatever it is applied to. Coatings and coating machinery is a technical skill so you should find qualified professionals who can provide you high quality coatings as well as the skill needed to apply them
