我查了壹下，國外的壹個網站在介紹高應力鎳的成因時提到間斷鉻這個概念，即：
在高應力鎳的表面按常規再鍍0.2~~0.3um的普通鉻層後，在鉻層與高應力鎳應力的相互作用處，高應力鎳層即產生大量微裂紋，並導致鉻層表面也形成均勻的微裂紋。此時的鉻層即成為微間斷鉻。據說這種塗層有較強的抗腐蝕性。
此外在其它網頁中也提到了它，妳自己看下吧：
A method with wide process margins for producing a plated-wire memory elet with both good unipolar disturb resistance and burst read resistance. The method comprises adding the additional process step of dipping the wire after the first permalloy layer or a portion thereof has been plated into a bath of a chromium chloride solution so that a thin, discontinuous chromium chloride film overlays this inner permalloy layer. The rest of the first permalloy layer (mated-film process) or the second permalloy layer (mated-film process) may then be plated over this chromium chloride film。

A discontinuous flash chrome interlayer of about 5 to 25 .ANG. is incorporated between the upper and lower magnetic recording alloy layers. This flash non-magnetic separation layer is so thin that it is, in fact, a discontinuous layer, so that while the benefits of having some chrome flashed on the surface of the first portion of the magnetic recording alloy are achieved, yet the upper and lower magnetic recording alloy layers are not completely physically separated as they are in disks made according to known sputtering processes.

The subject of the invention is a layer system for the decorative coating of galvanizable work pieces. In order to have a layer system which meets strict requirements with regard to corrosion resistance and which, at the same time, has a high abrasion resistance and, in addition, provides a high degree of freedom with regard to decorative coloration, the invention proposes a layer system which is formed by galvanic deposition and comprises a base coat consisting of at least one bright layer and one discontinuous chrome layer as well as a cover coat of mechanically resistant materials deposited by the PVD process.
