.... The objective of this study is to model the thermoelastic stress wave propagation inside the coating in laser-assisted cell direct writing when vaporization and/or optical breakdown of coating materials is/are not available. It is found that a bipolar pressure pair, with peak magnitudes on the order of 1 MPa...

... coating to the side surfaces of the cathode. The goal of this research was to find a durable coating for this process. Epoxy resins, Teflon, and diamond-like carbon are considered as dielectric cathode coatings. Different aspects of the working environment of these coatings in the pulse bipolar ECM...

... on the threading and the side cut turning. The inserts used for testing is the TiAlN coated and uncoated grades. LT22NR35ISO type insert is used in the experiment. During the experiments, no cutting fluid and a constant spindle speed is used. The thread pitch and the depth of cut were kept fixed at 3.5 mm and 0.05...

...Jyhwen Wang; Ritesh Shah; Yu-Hsuan Huang; Der-Form Chang Deformable coated materials hold promises for numerous new technologies. In this research, extrusion of polymer coated metal rods was investigated. Analytical models based on upper bound method were developed to evaluate axisymmetric conical...

... that reproduces the conditions encountered during production of engine-blocks made of a type 319 aluminum alloy. The surface roughness of the liners was modified by sand blasting before casting. Some of the liners were cast after coating their surface with an amorphous carbon layer (soot) to study its effect...

...Sunghyuk Park; Shiv G. Kapoor; Richard E. DeVor A model to predict failure of coated WC-Co grades due to chipping in intermittent cutting via microstructure-level finite element machining process simulation is presented and applied to various coated WC-Co tools. Coated tools were examined...

... the assumption of a homogeneous material deformation. Such assumption will be eliminated in Part II where the friction coefficient is more directly measured. Part I also investigates the validity of using high-strength/low-friction die coatings to improve the tribological characteristics observed in micro...

...Zhuang Fu; Yanzheng Zhao; Qinghua Yang This paper presents a prediction model of the adhesive coating thickness on a space solar cell. The model describes the non-Newtonian characteristics of the adhesive when it is bonded to the cover glass and the space solar cell in a non-vacuumed environment...

... in coating manufacturing processes. Among various coating techniques, high throughput within a coating manufacturing process can be achieved by depositing a thin film into a large area of continuous roll-by-roll flexible substrates. Although the recent development of in situ sensing provides an opportunity...
