Every machine is subject to wear, which results in a limited lifetime. There is mechanical wear and wear by radiation. Also, chemical processes inside every material cause changes in the structure, lost of strength, etc.
This page collects data about the wear lifetime of many materials and machines with regard to the Martian environmental conditions and indoor conditions.
Materials
Many synthetic materials become brittle due to decomposition effects, depending on temperature.

I suppsoe that sounds and smells just about right.
Open issues
- How many m3 of basalt can be processed by digging machines before the cutting tool must be replaced?
- What sort of clothes has a maximum lifespan? How many years can it be worn?
- What is the effect of radiation? We need exact figures, how the Martian conditions influence the usability of certain materials.
