By electroless deposition coatings of nickel-phosphorus alloys up to about 100 μm thick can be deposited onto metallic and nonmetallic substrates. At phosphorus contents between 2 and 8 mass% the coatings exhibit a nanocrystalline structure. The process of the deposition of such coatings is described. The microstructure of the coatings is analysed by using X-ray diffraction, transmission electron microscopy and field ion microscopy. As a result, the grain size of the coatings varies between 2 and 10 nm depending on the phosphorus content. When heated at a rate of 5 K/min, excessive grain growth occurs at a temperature between 350 and 400°C, when the equilibrium phase Ni3P is formed. In the as-deposited state the nanosized supersaturated nickel crystals seem to be surrounded by an amorphous phosphorus-rich phase. At 150°C a relaxation and an increase in the phosphorus content of the amorphous phase can be observed.
