Record 1 2022-03-16

English

Subject field(s)
  • Industrial Techniques and Processes
DEF

An additive manufacturing process in which focused thermal energy is used to fuse materials by melting as they are being deposited.

CONT

... additive manufacturing technologies... Directed energy deposition can come in many forms, but they all follow a basic process. Wire or powder material is deposited into thin layers and melted using a high-energy source, such as a laser.

OBS

... an energy source (for example laser, electron beam or plasma arc) is focused to melt the materials being deposited.

OBS

directed energy deposition; DED: designations standardized by ISO.

French

Domaine(s)
  • Techniques industrielles
DEF

Procédé de fabrication additive dans lequel l'énergie thermique focalisée est utilisée pour fusionner des matériaux en les fondant pendant leur dépôt.

OBS

[...] une source d'énergie (par exemple, laser, faisceau d'électrons, ou arc plasma) est focalisée pour faire fondre les matériaux pendant leur dépôt.

OBS

dépôt de matière sous énergie concentrée : désignation normalisée par l'ISO.

Record 2 2016-07-12

English

Subject field(s)
  • Industrial Techniques and Processes
CONT

Layer manufacturing technologies produce 3D physical parts directly from CAD [computer-aided design] solid models.... many system manufacturers have developed layer manufacturing technologies and techniques, with [stereolithography], selective laser sintering(SLS), fused deposition modelling(FDM), and 3D printing(3DP) being the most common.

French

Domaine(s)
  • Techniques industrielles
CONT

Procédés de prototypage rapide : stéréolithographie [...], frittage sélectif au laser [...], dépôt de [fil] en fusion (FDM), etc.

OBS

procédé SLS : L'abréviation «SLS» correspond au terme anglais «selective laser sintering».

Record 3 2016-06-01

English

Subject field(s)
  • Non-impact Printing
DEF

Printing performed using physico-chemical processes, rather than mechanical striking.

OBS

Some of the non-impact printing processes are ink-jet printing, thermal printing, electrographic printing, electrophotographic printing(e. g. laser printing), electrosensitive printing, magnetographic printing and ion deposition printing.

Key term(s)
  • nonimpact printing

French

Domaine(s)
  • Impression sans impact
DEF

Impression réalisée au moyen de procédés physico-chimiques, plutôt que par percussion mécanique.

OBS

Parmi les procédés d'impression sans impact, on compte notamment l'impression par jet d'encre, l'impression thermique, l'impression électrographique, l'impression électrophotographique (p. ex. l'impression au laser), l'impression électrosensible, l'impression magnétographique et l'impression à projection d'ions.

OBS

Bien qu'on trouve «impression non impact», il vaudrait mieux éviter ce terme qui semble calqué de l'anglais.

Spanish

Campo(s) temático(s)
  • Impresión sin impacto
DEF

Impresión efectuada por un conjunto de dispositivos, generalmente conectados directamente al ordenador, que generan la imagen sin que la forma impresora toque el soporte.

OBS

Ejemplos son la impresión láser, térmica, por inyección de tinta, sublimación, etc.

Record 4 2015-04-22

English

Subject field(s)
  • Industrial Techniques and Processes
CONT

Laser Deposition Technology(LDT) is a blanket name that encompasses many "like" processes—direct metal deposition(DMD), laser additive manufacturing(LAM), laser metal deposition, and others—that use a focused laser beam as the heat source for depositing powdered metals.

Record 5 2015-04-22

English

Subject field(s)
  • Industrial Techniques and Processes
CONT

Laser Metal Deposition(LMD) is a process which uses a laser beam to form a melt pool on a metallic substrate, into which powder is fed. The powder melts to form a deposit that is fusion bonded to the substrate. The required geometry is built up layer by layer. Both the laser and nozzle from which the powder is delivered are manipulated using a gantry system or robotic arm.

French

Domaine(s)
  • Techniques industrielles
CONT

Dépôt de métal par laser. Le laser assure le frittage ou la fusion. Une buse pulvérise la poudre métallique.

Record 6 2004-03-11

English

Subject field(s)
  • Chemical Elements and Compounds
CONT

Cr oxides - oxidative dissolution. Anodic polarisation leads to dissolution of CrIIIand CrIV oxides in both acidic and alkaline media.

CONT

We demonstrate that two phases CrO2 and Cr2O3 oxides can be grown by using laser initiated deposition(laser-induced Organic-Metallic Chemical Vapor Deposition(LMOCVD) and laser-induced deposition from solution(LISD), whose mechanism is similar to the first one but in solution and LISD has both advantages of chemical vapor deposition and electroless deposition). The magnetization measurements show that both chromium oxides are presented, and the relative weight of each phase depends on the experimental conditions such as oxygen partial pressure.

OBS

chromium oxide: A generic term which includes "chromium(III) oxide" and "chromium(VI) oxide" (q.v.).

French

Domaine(s)
  • Éléments et composés chimiques
CONT

Le Cr est l'élément primordial de la résistance à la corrosion; en effet dans les atmosphères uniquement oxydantes il se forme une pellicule d'oxyde de Cr qui ralentit la progression de l'oxydation jusqu'à une certaine température; [...]

CONT

Le Chrome sous forme d'oxyde Cr2O3 amphotère est utilisé en céramique pour ses propriétés colorantes, seul il donne des verts intenses. [...] L'oxyde de chrome est très réfractaire et résistant à la réduction, il est utilisé comme colorant pour l'estampillage sous couverte des porcelaines (1350-1400 °C).

CONT

Le groupe n° 3 : «composés trivalents du chrome» (Cr3+) (composés chromiques) incluant l'oxyde chromique (Cr2O3), qui est l'oxyde de chrome vert; [...]

OBS

oxyde de chrome : terme générique qui englobe l'oxyde de chrome(III) et l'oxyde de chrome(VI).
