The result indicated that the AlTiN multilayer coating deposited on high speed steel substrates with alternated nitrogen contents in layers. In each layer, AlTiN exhibited nanocomposites of nanocrystallites embedded into amorphous matrices despite of the nitrogen content. The difference between bilayers was that AlTiN layer with lower nitrogen content had a lower density of nanocrystallites. The AlCN coating deposited on Si (100) substrate appeared a strained layer on substrate in the ilm-substrate interface, which thickness was 3～5 atom layer.

结果表明：在高速钢基体上制备的AlTiN多层薄膜由两种氮含量交替变化的膜层构成，尽管交替的两层中氮含量不同，但每一单层都为纳米晶包含在非晶点阵中的纳米复合结构，不同之处是低氮含量层中纳米晶密度较小；生长在单晶硅基体(100)晶面上的非晶AlCN薄膜，在膜基界面处硅基体上出现应力畸变层，应力畸变层厚度很薄，约3～5个原子层。
