Recent advancements in metal fibers have introduced a promising new type of stainless steel fiber with high stiffness, high failure strain, and a thickness < 100 μm (<0.00394 in.) that can be utilized in a steel fiber-reinforced polymer. However, stainless steel is known to be susceptible to pitting corrosion. The main goal of this study is to compare the impact of corrosion on the mechanical p...

the present article considers the nd:yag pulsed laser welding of 304 stainless steels with two different compositions. the effects of various laser operational parameters and cooling rates on the weld microstructures were considered. the results show that ferritic solidification is produced in the stainless steel with the creq/nieq ratio of 1.7, and austenitic solidification is produced in the ...

Laser Powder Bed Fusion (LPBF) printing is used for manufacturing conformal cooling injection molds with internal channels. Currently, the steel to manufacture such by LPBF maraging 18Ni300. However, this softer at high temperatures and less resistant corrosion than reference steel, AISI H11. Moreover, 18Ni300 contains cobalt, an element that can be harmful health of people handling powders mad...

Numerous apex locator studies have been performed. Generally, they use only stainless-steel hand files for testing purposes. Today many clinicians use both stainless-steel and nickel-titanium files during the treatment of a case. Given the widespread use of nickel-titanium files, a comparison of the accuracy in determining length with an apex locator using stainless-steel and nickel-titanium fi...

This work explores the effect of surface modification of stainless steel with a carbon nitride (CNx) film, under sliding wear of the UHMWPE/steel. Wettatibility of CNx coatings is assessed by means of the sessile drop method using two different liquid media. Microhardness and stiffness of CNx coatings are estimated by depth-sensing indentation. The sliding performance of UHMWPE against stainles...

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...

Barrier layer material deposited on stainless steel substrate has been under investigation. These layers are part of a film-Si module, presently under development at ECN. Low temperature (< 250°C) processing is required in order to avoid impurity diffusion from the stainless steel foil. Novel materials based on nano particles combined with organic/ inorganic polymers and SiOx precipitated from ...

We investigated the wear characteristics and clinical performance of four different total hip joint articulations in 114 patients. Wear and migration was measured by roentgenstereophotogrammetric analysis at five years or at the last follow-up. The mean annual wear was 0.11 mm for a stainless steel/Enduron articulation, 0.34 mm for stainless steel/Hylamer cup, 0.17 mm for zirconium oxide cerami...

Bulk phase transformations and dislocation density were monitored in a maraging stainless steel on bulk level using in-situ neutron diffraction up to 1340 °C, i.e. 30 °C below the melting temperature. Three materials with different initial microstructure and/or composition studied: wrought, as-built SLM-ed (selective laser melted) re-austenitized SLM-ed. In contrast wrought martensitic steel, w...

driver (Figure 1), is made from stainless steel and is used to hold a suturing needle during surgical procedures. To maintain a firm grip on the needle, the jaws have textured patterns either etched directly on the stainless steel or on a replaceable tungsten carbide insert, which grips the suture needle more precisely and wears out much slower than stainless steel. Needle holders with tungsten...
