Front

Deterioration of a metal caused by a chemical attack or electrochemical reaction with dissimilar metals in the presence of a solution containing electrolytes.

Back

Corrosion

Front

Discoloration resulting from the oxidation of a thin layer of metal on its surface. Not as destructive as corrosion.

Back

Tarnish

Front

An electric current transmitted between two dissimilar metals in a solution of electrolytes.

Back

Galvanism

Front

A change in the size of matter

Back

Dimensional Change

Front

The measurement of change in volume or length in relation to change in temperature

Back

Coefficient of Thermal Expansion

Front

The movement of fluid in the microscopic gap of a restoration margin as a result of differences in the expansion and contraction rates of the tooth and the restoration with temperature changes associated with the ingestion of cold or hot fluids or foods.

Back

Percolation

Front

The rate at which heat flows through a material.

Back

Thermal Conductivity

Front

Materials with low conductivity

Back

Insulators

Front

The production of heat resulting from the reaction of the components of some materials when they are mixed.

Back
