Introduction Failure of engineering materials often begins at the surface, thus optimizing the structure and properties of the surface layer may substantially improve the overall behavior.
The process is more complex, if a soft surface is coated with a harder material, such as aluminum with hard oxides [14].

Plasma Monitor and Material Characterization.
As reported by Buijnsters et al.,[10], UNCD is a highly light absorbing material because it is synthesized with a high renucleation rate and composed of a relatively high fraction of sp2-bonded carbon connecting the grains.
Correlation between materials grown and gas-phase species present in the plasma is important to identify the species driving the process mechanism.

Using biodegradable materials.
Using recycled and/or recyclable materials. - Prioritizing the use of low-impact materials considering the largest possible number of stages of the product life cycle
DFA, DFD, DFM and DFRR … Strategy DFE - Plan End-of-life Production Avoiding the union of incompatible materials. - Facilitating the disassembly and separation of materials
DFD and DFR Identifying the materials that compose the products. - Positioning data about materials visibly and preferably directly on the product.* - Providing information to the user about the correct disposal of the product.* - Identifying materials according to ISO14021:1999.* - Providing additional information such as number of recycling made ​​or additives used in the composition of the materials.
The evaluation of the products presented in the three cases, the excessive use of materials besides incomplete information about the materials used and the correct way of disposal.

The properties of the three materials are listed in Table 1.
Similar results were found for other materials and shapes under load.
These results show that landing gear made with the above materials does not exceed the yielding or maximum stress and strain of the material, under different static loads.
Landing gear of different materials and different shapes also exhibit similar results.
The results of the dynamic load test show that landing gear of different materials and shapes have different characteristics.
