Title: Hiromi Yamauchi: Innovator in Chrome Plating Technology

Introduction

Hiromi Yamauchi is a distinguished inventor based in Aichi-ken, Japan. She has made significant contributions to the field of chrome plating technology. Her innovative approach has led to the development of a unique method that enhances the properties of chrome plated parts.

Latest Patents

Yamauchi holds a patent for "Chrome plated parts and chrome plating method." This invention utilizes a chrome plating bath containing organic sulfonic acid. By applying a pulse current, a crack-free lower chrome layer is formed on a steel substrate. This lower chrome layer exhibits a compressive residual stress of 100 MPa or more and a crystal grain size ranging from 9 nm to less than 16 nm. Following this, a direct current is applied to create a cracked upper chrome layer on the lower layer. This innovative process results in a chrome plated part that possesses enhanced heat resistance, corrosion resistance, wear resistance, and good sliding properties.
