microwelds
Microwelds are tiny metallurgical bonds formed between contacting surfaces under high pressure and temperature. These bonds can increase friction by creating adhesion between the surfaces, leading to stiction. However, in some cases, microwelds can also reduce friction by providing contact points that distribute load and reduce surface roughness.
The force caused by tiny collisions called microwelds on surfaces that are stuck together is called friction. Friction is the resistance to motion when two surfaces are in contact with each other. Microwelds are small points of contact where atoms on the surfaces bond together, creating resistance to movement.
bumps from two surfaces come into contact.

the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .
The force caused by tiny collisions called microwelds on surfaces stuck together is known as adhesion force. These microwelds form when the surfaces come into close contact, creating intermolecular attractive forces that hold the surfaces together.
Friction is created when bumps from two surfaces come into contact, which resists motion and generates heat.

When bumps from two surfaces come into contact, they can create friction, which is a force that resists the motion between the two surfaces. This friction can lead to heat generation and wear on the surfaces.
