Two reasons: there's more surface area at a joint, and the joint gives water a place to get trapped.
20 gauge galvannealed steel will rust faster in salt water compared to fresh water. The presence of salt in salt water accelerates the corrosion process of the metal, leading to faster rust formation.
In a medium of lower pH (acidic), the rate of corrosion is high. If the pH of medium is below 3 (approximately), even in absence of air severe corrosion takes place due to rapid evolution of hydrogen at cathodic areas, facilitating anodic oxidation of the metal and dissociation of corrosion product, exposing fresh metal surface for corrosion. In distilled water (pH about 7), rate of corrosion is relatively lower.
Corrosion is a chemical reaction. The vast majority of chemical reactions are speeded up by the input of heat. The energy from the heat causes the particles to move faster and thus react faster.
A great starting point to learn about corrosion is on the National Corrosion Society web page. They provide in-depth explanations of what corrosion is and how it forms. They also provide monthly newsletters on the latest developments to fight corrosion.
There are two general types of joints, movable and immovable. Under the movable category there are four types of joints: Hinge joints: in knees and elbows Pivot joints: in neck Gliding joints: in wrists and ankles Ball-and-socket joints: in shoulders and hips
yes, it can not only lead to corrosion but a faster corrosion.
Corrosion which is an oxidation reaction needs oxygen and water. Water in the form of condensation is readily available in cold areas. Hence corrosion go faster in cold areas.
The one that has the strongest oxidizing agent.
Mesh
Titanium and cobalt-chromium alloys are commonly used to make artificial joints for bones due to their biocompatibility, strength, and resistance to corrosion.
(metallurgy) Corrosive degradation of metal parts at the crevices left at rolled joints or from other forming procedures; common in stainless steel heat exchangers in contact with chloride-containing fluids or other dissolved corrosives. Also known as contact corrosionRead more: crevice-corrosion

The salt contains ions, which increases the rate of corrosion or oxidation of steel.
It's often faster and can be stronger too.
Fretting corrosion is most likely to occur in situations where there is repetitive movement or vibration between two contacting surfaces. This movement can lead to the removal of protective oxide layers on the surfaces, exposing them to corrosion. It is common in mechanical components like bolted joints, bearings, and electrical connectors.
The Upper limb heals faster than the Lower limb, this is because there is more blood flow at the Upper, so basically where there is more blood the faster they heal.
How long a CV joint lasts is directly proportionate with how you drive your car. If you corner hard and accelerate hard, your CV joints won't last as long as the CV joints in a car that has been driven in a more conservative manor.
