Plasma Electrolytic Oxidation (PEO) and Hard Anodizing (HA) coatings are investigated on an Additively Manufactured (AM) Al10Si1Mg alloy obtained via Direct Metal Laser Sintering (DMLS). Results compared to those for a conventional A361 cast alloy. Findings revealed that the microstructure of AM alloy, consisting α-Al cells enclosed in Si network, produces more uniform –in terms morphology, thi...

We present a case study where we use automated formal analysis to reason about problem-frame concerns. The descriptions of the problem domains, machine and requirements are written in the Alloy language. We show that an evaluation of results and counterexamples provided by a model finder can reveal useful information that can help remove inconsistencies as well as composition errors.

BACKGROUND Several methods that are currently used for contouring analysis have problems providing reliable and/or meaningful results. In this paper a solution to these problems is proposed in a form of a novel measure, which was developed based on requirements defined for contouring studies. MATERIALS AND METHODS The proposed distance deviation measure can be understood as an extension of th...

Using density functional theory (DFT) calculations and angle-resolved photoemission spectroscopy (ARPES) the structural electronic properties of graphene on surface subsurface Co–Ir alloy are investigated upon intercalation Co in graphene/Ir(111). It is found computationally that interaction strength between substrate strongly affected by composition nature an alloy, implying large difference s...

This paper concentrates on the degradation characteristics of hydroxyapatite (HA) coatings on orthopaedic Ti-6Al-4V alloy while immersed in Ringer's salt solution, which were investigated by electrochemical impedance spectroscopy. Electrochemical impedance spectroscopy measurements were used to in situ characterize the electrochemical behavior of the passivated alloy covered with HA during agin...

Friction stir lap welding (FSLW) raises the possibility of fabricating high-performance aluminum components at low cost and high efficiency. In this study, we mainly applied FSLW to fabricate multi-track 2024 aluminum alloy without using tool tilt angle, which is important for obtaining defect-free joint but significantly increases equipment cost. Firstly, systematic single-track FSLW experimen...

This paper investigates the effect substrate preparation has on epoxy mold compound (EMC) adhesion to bare copper leads. There have been four basic strategies employed to characterize and subsequently improve adhesion between the EMC and copper: 1. Choosing a particular copper alloy, i.e. varying alloy effects in copper to improve oxidation control and thus adhesion. 2. Modifying the mold compo...
