A Hot-wire Engine to Produce Periodic Grooves on an Ice Surface

  • T.M. Tobin (a1) and K. Itagaki (a1)

Abstract

A strain-tree grooving method has been developed for surface self-diffusion studies of ice. This method utilizes a hot-wire grooving engine and is capable of obtaining a uniform spacing between grooves ranging from 15.9 μm to 159 μm in increments of 15.9 μm.

Résumé

On a mis au point une méthode pour graver des lines rainures dans la glace sans lui faire subir d’efforts, en vue d’études sur l’autodiffusion de surface dans la glace. Cette méthode utilise un appareil de gravure à fil chaud et permet d’obtenir un espacement régulier entre les rainures variant de 15,9 μm à 159 μm par paliers de 15,9 μm.

Zusammenfassung

Eine Methode zur spannungsfreien Riefelung für Studien der Eigendiffusion an Oberflächen von Eis wurde entwickelt. Die Methode verwendet ein Heizdraht-Riefelgerät, das Rillen mit gleichmässigen Abständen von 19.9 μm bis 159 μm in Schritten von 15.9 μm zu erzeugen gestattet.
