Title:
REACTOR APPARATUS AND ITS SURFACE MODIFICATION METHOD
Document Type and Number:
Japanese Patent JP2009210285
Kind Code:
A
Abstract:
To provide a reactor apparatus and its surface modification method capable of preventing surely beforehand generation of an SCC damage form by improving simultaneously a material factor and a stress factor for SCC generation prevention in a material to be executed.
In this reactor apparatus, a surface modification layer is constituted, wherein a highly corrosion-resistant layer serving simultaneously as a compressive stress layer for compressive stress application is achieved in a high-temperature high-pressure fluid environment, on a material surface part of the material to be executed such as a reactor internal structure or piping.
