Abstract: Compressive residual stresses induced by mechanical surface treatment such as shot peening, autofretage, hole expansion, laser shock peening, and low-plasticity burnishing can be highly beneficial to fatigue resistance. Cyclic relaxation of compressive residual stress, however, reduces the benefit. An analytical model is proposed for estimation of residual stress relaxation. Parameters considered by the model include the magnitude and distribution of the residual stress, the degree of cold working required, the applied alternating and mean stresses, and the number of applied loading cycles. An elasto–plastic finite element model was used to demonstrate the model.

Abstract: An apparatus for use as a catheter guidewire and a method for making a catheter guidewire. The apparatus comprises an elongate non-coiled wire having a proximal portion, a distal tip and a flexible portion located between the proximal portion and the distal tip having axially spaced grooves cut therein. The method for making the guidewire includes burnishing one end of a wire to create a rounded distal tip and cutting a predetermined pattern of axially spaced grooves in a length of wire adjacent to the distal tip to create a flexible portion.

Abstract: In the ultra precision diamond cutting process, the rake angle of the tool is likely to become negative because the edge radius of tool is considerably large compared to the sub-micrometer depth of cut. The round edge of the tool might sometimes cause plowing results in a poor surface, or burnishing which results in a shiny surface depending on the depth of cut. This study deals with the relationship between the friction of a tool-workpiece and the minimum cutting thickness in micro cutting. Proposed is an ultra precision cutting model in which the tool edge radius and the friction coefficient are the principal factors determining the minimum cutting thickness with a continuous chip. According to the model, a smaller edge radius and a higher friction coefficient make the cutting depth thinner. The experimental results verify the proposed model and provide various supporting evidence.

Abstract: Solid lubricant systems were developed to provide friction and wear reduction in variable environmental conditions. The mechanisms employed to achieve cross-environment capability include “on demand” solid lubricant supply from reservoirs in hard wear protective coatings. This research explores recent advances in a precision laser machining to generate arrays of micrometer sized dimple reservoirs with controlled size, location, and density. These micro-reservoirs were machined by a focused UV laser beam on the surface of hard TiCN coatings produced by a cathodic vacuum arc deposition. Different dimple diameters and spacing were used to achieve area coverage with micro-reservoirs between 0.5% and 50% of the entire tribological contact surface. Solid lubricants based on MoS2 and graphite were then applied by burnishing and sputtering to such laser textured surfaces. Sliding friction tests were performed against steel balls in humid air and dry nitrogen environments. The results indicate that there is an optimum dimple surface coverage of about 10%. The life of the solid lubricants on dimpled surfaces was an order of magnitude longer than on the unmodified TiCN coating surface. The laser-processed micro-reservoirs also helped to renew lubricant supply for tests with multiple cycling between humid air and dry nitrogen. Tribological surface adaptation to the test environment was investigated by micro-Raman, which demonstrated a repeated change from hexagonal MoS2 to graphite carbon in the wear track with each dry/humid environment cycle. Solid lubricant composition inside the micro-reservoirs did not change.

Abstract: Grain refinement and strong basal texture were produced on AZ31B Mg alloy surface concomitantly by a newly developed severe plastic deformation (SPD) process, severe plasticity burnishing (SPB). The remarkably improved corrosion resistance of AZ31 in NaCl solution after SPB was attributed mainly to dramatically reduced grain size and strongly basal-textured grain orientation. The residual stresses introduced by SPB were also found to influence the corrosion resistance to some extent. Compared with other SPD processes, SPB is fast, cost-effective, does not change material bulk properties and requires little changes to the industrial production process.
