Abstract
In a thermally sprayed, gastight protective layer for metal substrates, such as Fe, Ni, Al, Mg and/or Ti, the spray powder for the purpose includes at least two components. The first is a silicate mineral or rock and the second is a metal powder and/or a further silicate mineral or rock. The silicate mineral or rock component in the spray powder has an alkali content of less than 6 percent by weight.
