Many factors affect the DLC coating performance such as hydrogen content [1], humidity [2] or element doping [3,4].
The doping of DLC with different metals (Ti, Fe, Mo) leads to the changes in the mechanical properties (lower stress, improved adhesion) and tribological properties (lower friction coefficient).
Results and Discussion Tribological properties of CNT doped DLC films.
Another factor affecting the scratch process is the weight percentage in CNTs.
For mechanical and tribological properties, the addition of CNTs during deposition increases ID/IG ratio and reduces friction coefficient and critical load.

Table.2 Vibration properties of the radiogram Experimental result Finite element analysis (Hz) Natural frequency (Hz) Transmissibility 185.47 3.09 183.45 (6th) 247.23 7.66 249.31 (10th) Analysis of impact response property Drop shock response of prime component Considering the prime damageable component within the product system, the mechanical model of package article may be simplified into two degrees of freedom including one degree of freedom for the prime damageable component, and the acceleration of prime damageable component () is the product of the excitation acceleration () and the amplification factor () [10] (1) And the amplification factor wound be selected the bigger one from the following calculations (2) (3) Where is the ratio of natural frequency () of main part of package article to the prime damageable component ().
By analyzing and comparing these results and curves, some conclusions may be drawn as follows: (1) the magnitude of amplification factor depends on the ratio of natural frequency of the radiogram to the equivalent frequency of impact load, and it is bigger than 0.5, so the amplification factors in Fig.2 are bigger than one. (2) For the impact duration 2.02ms (nearly causing the resonance of radiogram), and the amplification factor markedly rise more than two even three.

By considering increasing dynamic and static energies, the physical and mechanical properties are analyzed for each case.

This phenomenon results in a minimal heat-affected zone (HAZ) and a reduced volume of melted material, limiting structural changes and thermal deformation compared to arc welding methods, which can adversely affect material properties [3,4,5].
These factors often lead to defects such as porosity, hot cracking, and softening of the welds, thereby compromising joint integrity [6,7,8].
This led to a better understanding of the mechanisms affecting weld quality and the optimization of welding parameters.
