Sacrificial Anode

Atkins has had those for years.

also that definition is kinda lacking.

electrochemical process is due to the creation of a cell between two points. One side is oxidized (the anode), as it gives up electrons (and losses mass since atoms are ionized into solution) which then reduce a different spot (the cathode) where material from solution builds up. Use of an a sacrificial anode ground into the block (cant be in plastic) essentially changes what the anode is in the voltaic cell. It can still form between two points on a surface as well which is how rust forms as Fe forms a cell with itself.

weirdly, my expresso maker has this problem.
