in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...

We report on the first encapsulated rotary ball bearing mechanism using silicon microfabrication and stainless steel balls. The method of capturing stainless steel balls within a silicon race to support a silicon rotor both axially and radially is developed for rotary micro machines and MEMS ball bearing tribology studies. Initial demonstrations show speeds up to 6.8 krpm without lubrication, w...

OBJECTIVE To evaluate the quantitative effects on torque expression of varying the slot size of stainless steel orthodontic brackets and the dimension of stainless steel wire, and to analyze the limitations of the experimental methods used. MATERIALS AND METHODS In vitro studies measuring torque expression in conventional and self-ligating stainless steel brackets with a torque-measuring devi...

Recent advances in additive manufacturing (AM) techniques (otherwise known as 3D printing) have enabled fabrication of a new class of porous biomaterials (Figure 1) with arbitrarily complex and precisely controlled topologies that e.g. resemble the geometry and micro-architecture of (trabecular) bone. Since the geometry of scaffolds and biomaterials is an important factor in bone tissue regener...

The interaction between the surface of stainless steel and Bacillus cereus was studied in terms of the characteristics of interfacial interaction determined from the measurement of the contact angle of the surface of B. cereus and stainless steel in the presence or absence of B. cereus adherence. The microtopographies and the roughness of the surface of stainless steel and stainless steel adher...

Powder metallurgy (P/M) technique is usually used for manufacturing porous metal materials. However, some P/M materials are limitedly used in engineering for their performance deficiency. A novel 304 stainless steel P/M material was produced by a solid-state sintering of 304 stainless steel powders and 304 short stainless steel fibers, which were alternately laid in layers according to mass rat...

The 316L stainless steel has been widely used in both artificial knee and hip joints in biomedical applications. The average lifetime of artificial hip joints is about 10 years due to aseptic loosening of the femoral stem attributed to polymeric wear debris; however, there is a steadily increasing demand from younger osteoarthritis patients aged between 15 and 40 years for a longer lasting join...

A self-developed rotary multi-cutter device cuts stainless steel wire ropes into segments to fabricate twisted wires. Stainless steel porous twisted wire materials (PTWMs) with a spatial composite intertexture structure are produced by the compaction and subsequent vacuum solid-phase sintering of twisted wires. The stainless steel PTWMs show two types of typical uniaxial tensile failure modes, ...

Stainless steel and graphite electrodes were individually addressed and polarized at −0.60 V vs. Ag/AgCl in reactors filled with a growth medium that contained 25 mM fumarate as the electron acceptor and no electron donor, in order to force the microbial cells to use the electrode as electron source. When the reactor was inoculated with Geobacter sulfurreducens, the current increased and stabil...
