Abstract The contact length is one of the most important factors to evaluate chip formation process and mechanical loads in metal cutting. Over years, several methods identify were developed. However, especially for wet cutting processes determination still challenging. In this paper, three dry Ti6Al4V AISI4140 + QT are presented, discussed analyzed. first approach uses tools with a microtextur...

Polycrystalline textured thin films with distinct pleochroism and birefringence comprising oriented rotational domains of the orthorhombic polymorph an anilino squaraine isobutyl side chains (SQIB) are analyzed by imaging Mueller matrix ellipsometry to obtain biaxial dielectric tensor. Simultaneous fitting transmission oblique incidence reflection scans combined spatial resolution optical micro...

Abstract This work considers the possibility of controlling thermally sprayed TBC columnar microstructure using metallic bond coat microtexturization prior to ceramic top spraying. Such pretreated has been modeled investigate influence substrate topography on behavior plasma stream and resulting movement feedstock particles in closest proximity substrate. The analysis considered microscale comp...

and the inability to tune the size of the features independent of the mold. Here, we seek to employ soft lithography to develop robust chemically bound coatings with microscale surface features of tunable heights. This paper describes the combination of soft lithographic molding and a surfaceinitiated polymerization (SIP) to produce a versatile process termed micromolding surface-initiated poly...

The inspection of titanium billets and forged parts with conventional immersion and laser-ultrasonic techniques was performed to localize macro-zones with strong texture. The microtextured regions in these dual phase titanium parts were detected by using backscattered noise measurements. A numerical focusing technique was developed for imaging the backscattered noise in parts with curved surfac...
