Tribological properties of a-C:H coatings were conducted used reciprocating friction tester.
Introduction Diamond-like carbon (DLC) coatings have emerged as attractive coatings for mechanical, chemical, electrical, tribological properties [1-4] and their suitability for a wide range of practical applications.
As the current applied on the filament affects the ionization rate of the hydrocarbon reaction gas.
Tribological properties Figures 2 and 3 illustrate the influence of the tungsten filament current on the tribological properties of the a-C:H coatings.
The optimum coating for tribological properties against a AISI 52100 steel or a Al2O3 ball is 17A coating.

These features, combined with the high strength properties and fracture toughness, provide better properties to this family of steels, as compared to high-resistance carbon steels [5].
The reverted austenite formed in the interdendritic areas is not hardened by aging due to its stability and would require a subsequent heat treatment (annealing) to try to recover the mechanical properties of this region [14,15].

In the chemical vapor deposited zinc sulfide, it often appears obvious light and dark growth bands along the growth direction, which will affect the homogeneity of optical properties of CVD ZnS and the efficiency of subsequent heat treatment.
Its unique set of properties extends its usefulness to long-wave infrared window material and all-wave photoelectric window material.
Scattering is the main factor affecting the visible-light transmittance of CVD ZnS.

Many studies have successfully applied near infrared (NIR) spectroscopy to estimate important wood properties.
Several studies have demonstrated that NIR spectroscopy can be used to estimate wood physical and mechanical properties such as density, moisture distribution, wood stiffness and microfibril angle (MFA)[1-6] and chemical properties such as klason lignin content, acid-soluble lignin content, decay and extractive content[7-11].
The crystallinity has an effect on the mechanical properties of cellulose fibers.
And now, it has been shown that near infrared (NIR) spectroscopy and partial least squares (PLS) regression can be used to estimate the physical and mechanical properties of wood much more rapidly and conveniently, although with lower accuracy.
For the calibration set, the correlation increased with increasing of number of factors range from R2=0.2930 to R2=0.9566, and the RMSEC and SEC decreased with increasing of factors number until using six factors.

The fracture properties of FFF-printed parts are influenced by several factors, including material type, layer adhesion, print orientation, and infill density.
Understanding these factors is crucial for optimizing the fracture resistance of FDM-printed components in various applications.
Main mechanical properties are highlighted by the seller (SC ATELIER CONCEPT & DESIGN STUDIO SRL) in Table 1.

Numerical Study of Welding Sequence on the Residual Stress Field in a Thick-walled Tee Joint Wei Jiang1, a 1School of Mechanical Engineering, Dalian University of Technology, Dalian, China ajiangwei@dlut.edu.cn Keywords: Welding sequence, Residual stress, Multipass welding, Tee joint Abstract.
Finite element simulation is an efficient method for studying factors affecting weld-induced residual stress distributions.
It is found that welding sequence did not have a significant influence on the distribution pattern of the longitudinal residual stress; however, it did affect the peak values.
Fig. 1 FE model of a thick welded piping intersection Fig. 2 Temperature dependent material properties A total of six passes was assumed to fabricate the tee joint.
Temperature-dependent thermal and mechanical properties, which were assumed to be the same for both the base and weld materials, up to melting point, are shown in Fig.2[6].

Thus it is possible to realize the combination of excellent mechanical properties and electrical functionality for various types of substrate materials.
Me-DLC coatings are also expected to have high gauge factors.
The gauge factors for W-DLC coatings were rather low compared with the gauge factors for non-doped DLC coatings reported previously.
However, experimental investigations on the structure and mechanical properties of such double-layered structures have only just begun.
An overcoat to provide protection against mechanical loading or friction needs to be made harder by considering the deposition condition, precursor gas and other factors.
