Data analysis encompasses 69 powder properties, 15 process parameters per print, and 78 part features, culminating in a dataset of over 1.2 million correlations.

A series of state-of-the-art techniques are employed to evaluate the microstructural properties. This includes the quantification of residual strain (via neutron and X-ray diffraction), substructure development (via electron microscopy), porosity (via X-ray tomography), and microhardness (via indentation). The important findings are: 1) The AP sample features characteristic distributions of residual strain (i.e., tension around the cylinder edge, compression toward the core) and numerous pores; 2) postprocessing via HRS homogenizes the microstructure and eliminated porosity, while CRS causes significant grain refinement and increase in the microhardness but does not significantly reduce porosity; 3) impact deformation induces intensive hardening in the CRS and HRS sample, that they show up to 380 HV1 and 420 HV1 in microhardness; 4) on the contrary, the AP material retains its homogeneity after impact deformation.

High activity is generated by heating the loaded support to 50 °C. The prepared dUHMWPE powder has a bulk density of 0.26 g mL⁻¹. Thermal analysis, comprising fast and slow heating, holding, and cooling procedures, shows that the initial high state of disentanglement is not lost on melting and that crystallization from the melt basically reestablishes this state. Thermal treatment at 110 °C of the powder is possible without loss of the low viscosity to yield more compact particles (0.30 g mL⁻¹).

The results indicate that the co-deposition process can effectively inhibit the generation of large particles during arc deposition, thereby improving the density and uniformity of the coatings. The frictional performance of the coatings was enhanced by the incorporation of Cu due to its self-lubricating property. With the doping of Cu, the wear mechanisms of the ZrCuN coating changes intense abrasive and adhesive wear to slight adhesive wear. The wear rate of ZrCuN coatings is effectively reduced as compared with ZrN coatings by arc deposition. At a HiPIMS power of 1.5 kW, the wear rate was just 4.95 × 10⁻⁶ mm³N⁻¹ m⁻¹, which shows a 78.8% reduction as compared to that of ZrN coatings.

A chemical reaction between the particles, namely ilmenite, and silicon of the base alloy produced strong interfacial bonding, as shown by X-ray diffraction analysis.

The results indicate that M₂B-type borides preferentially grow along the [001] direction at a bonding temperature of 1220 °C. Increasing the matrix orientation deviation from 0° to 45° reduces the number of preferentially grown borides and leads to a dense distribution of small borides near the isothermal solidification zone/DAZ interface.
