Conclusions
-
1.
The hydrogen content in chemically reduced Ni-B coatings is ≈0.02%, regardless of the amount of boron in the alloy.
-
2.
The rate of evolution of hydrogen during the heating of the coatings is related to the structural-phase transformations that occur in them.
-
3.
A comparison of the data on the evolution of hydrogen with thermographic data gives a basis for believing that the hydrogen contained in the coatings is partially present in the atomic state, partially in a protonated state.
-
4.
The laminarity detected for certain coatings is considered as a consequence of a periodic variation in the ratio of the rates of reduction of nickel and boron, which are inversely dependent on the acidity of the medium.
