“…Histological analysis is usually done at the end of an in-vivo study, where it needs a sacrifice of the animals [54], or a biopsy of the target tissue while the animals are still alive [52]. The harvested tissue is then processed to obtain serial micro-slicing samples of the area of interest, either with or without the retrieved implant in the tissue.…”

“…By comparing the images of tissue around the implant to those of control tissue obtained from sham animals, the tissue-implant interaction can be analyzed. This can be done by observing the morphology, number and function of cells that were directly or indirectly in contact with the implant under an optical microscope, SEM, or confocal laser scanning microscope ( Figure 3a) [54][55][56]. The remnant of corrosion products can be viewed and measured in terms of size and distance from the implantation site ( Figure 3b) [57].…”

Absorbable metals have been introduced as materials to fabricate temporary medical implants. Iron, magnesium and zinc have been considered as major base elements of such metals. The metallurgical characterization and in-vitro corrosion assessment of these metals have been covered by the new ASTM standards F3160 and F3268. However, the in-vivo corrosion characterization and assessment of absorbable metal implants are not yet well established. The corrosion of metals in the in-vivo environment leads to metal ion release and corrosion product formation that may cause excessive toxicity. The aim of this work is to introduce the techniques to assess absorbable metal implants and their in-vivo corrosion behavior. This contains the existing approaches, e.g., implant retrieval and histological analysis, ultrasonography and radiography, and the new techniques for real-time in-vivo corrosion monitoring.

“…The aramid pulp fibre even melts as temperature continuously increases due to the heat accumulation of friction. And therefore molten aramid pulp fibre acts as lubricant and provided lubricating effect . Meanwhile, the carbon fibre is stretched and grinded by shear force and changed into similar graphite particles.…”

In this study, the cashew nut shell oil modified phenolic resin based friction materials reinforced by aramid pulp/glass/carbon fibres (constant content 17 vol.%) are prepared by hot pressed sintering method, and the effect of different fibres on tribological properties of resin matrix materials is studied. The tribological properties of friction materials are carried out by a ring‐on‐block tribo‐tester sliding against AISI 51200 steel ring under different braking loads and speeds. The friction coefficient and wear rate increase with the increase of load and speed. The synergistic effect of aramid pulp fibre and carbon fibre improves the tribological properties of friction materials. However, the friction coefficient and wear rate increase as the glass fibre increases. The specimen with 9%/1%/7% of aramid pulp/glass/carbon fibres shows more reasonable friction coefficient (0.31–0.50) and lower wear rate (4.5–7.9 × 10−6 mm3 N−1 m−1) than that of commercial friction material.

“…In many processing technologies of pure iron in recent decades, there were some reports on laser welding of pure iron; laser welding has the outstanding advantages of good processing stability and high processing efficiency, it has been widely used in the field of material processing . Nasution et al reported that the most widely used welding technology for pure iron was friction stir welding (FSW).…”

A vibration‐assisted laser welding experiment of 4.5 mm industrial pure iron is conducted to focus on the influences of vibration parameters on microstructure, fatigue fracture, and fatigue life. The studies show that the microstructure of the joint is optimized under the condition of 1186 HZ vibration frequency and 36.1 m s−2 vibration acceleration; it is also found that a suitable microvibration process can enhance the penetration depth of the joints, reduce the number of columnar crystals, and homogenize the microhardness. In high‐cycle fatigue experiments, the base material (BM) produces fatigue fracture only under the fatigue load of 52% Rm, the fatigue source area under vibration is at the corner of the fracture or at the inside of the weld seam; a functional consequence is that the vibration can increase the fatigue load strength by 1–3 percentage points, and the fatigue life can be increased by 0.8–1.5 multiples. The microvibration can effectively improve the fatigue performance and increase the fatigue life.
