  This book is a compilation of Durer's works in engraving, etching, and drypoint, with historians' and critics' comments on each image. Except for 15 images, all are reproduced at full size. There are 12 pages of introduction, notes, and list of plates, 7 pages of bibliography and index, 5 pages of images formerly attributed to Durer, and 1 page Cited by: 6. The book is divided into two sections: the wet and dry etching processes are presented in the first, general, section, which provides the scientific fundamentals, while a catalog of etching bath composition, etching instructions, and parameters can be found in the second section. etching a wide range of iron-, nickel-, and cobalt-base alloy systems. The following discussion of-fers guidelines for processing stainless steels, high temperature alloys, tool and alloy steels, and mag-netic and expansion alloys. Etchant selection Selection of the proper etchant depends largely upon alloy composition, heat treatment, and pro. The wet etching process is either isotropic (orientation independent) or anisotropic (orientation dependent), as shown in Fig. Usually, most wet etching processes are isotropic, which are adequate for geometries of greater than 3 μm. In isotropic wet etching [32], material is removed uniformly from all directions by HF or buffered HF solutions (NH 4 F and HF mixture).

The difficulty in etching these materials has focused attention also on employing the most effective procedures for etching a wide variety of iron-, nickel- and cobalt-based alloy systems. Ensuing discussion, therefore, will offer guidelines for processing stainless steels, high temperature alloys, tool and alloy steels, and magnetic and.

Sorby, in his classic work published in "On • Selection of the best etch composition • Control of etchant temperature and etch . Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching.

Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In modern manufacturing, other chemicals may be used on other types of material. As a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. Al etching start and thus to diff erent etching depths or times (Fig. ). The formation of hydrogen in the etching reaction is also problematic for a homogeneous etching result. The constantly produced H 2 bubbles stick to the surface and block the etching process through a sup-pressed supply of fresh etching medium. Cubist Composition, c.
