However, compared to the conventional potassium fertilizers, crushed or ground potassium-feldspar rocks exhibit a much slower potassium release [5-6]and the effectiveness is relatively lower and a large amount of materials have to be applied to meet crop needs [7].

The substrate material has great influence on film's hardness, binding energy and surface modification.
The targets material is titanium, purity: 99.99%, and the working gases are N2 and C2H2, purities are all 99.999%.
(3) The substrate material has great influence on films' hardness, binding energy and surface modification.
The closer the characters of film and substrate material are, the more remarkable the surface modification effect of film is.
