According to Rabinowicz theory [3], because of the materials with small elastic modulus E can store elastic deformation energy, and the materials with high hardness H and small elastic strain limit usually display excellent friction properties in wear.
In order to improve the interface strength between DLC film and substrates, it has been considered to use intermediate materials.
The results obtained are as follows: 1) When DLC film is directly deposited on surface of metal materials at room temperature, cracking is formed and local shedding is also generated on surface of film.
