Sandrine Henry

Title: Sandrine Henry: Innovator in Camshaft Technology

Introduction

Sandrine Henry, an inventive engineer based in Saint-Paul-en-Jarez, France, has made remarkable contributions to the field of mechanical engineering through her innovative patents. With a total of two patented inventions, her work primarily focuses on enhancing the efficiency and performance of camshafts and piston pins.

Latest Patents

One of Sandrine Henry's latest patents is for a method of coating the nose of the cams of a camshaft with Diamond-Like Carbon (DLC). This innovative method aims to reduce the friction coefficient of the cams in comparison to a counterpart in areas equipped with a hard DLC coating. The process involves placing the cams on a support, which is then placed in a vacuum chamber for cleaning. Following this, the support undergoes relative movement along a trajectory to a coating source, allowing for selective deposition of hard DLC coating on the appropriate sections of the cams. This precise configuration ensures that the cams achieve a uniform coating, enhancing their overall performance.

Another significant invention by Henry is the piston pin designed with an anti-seize coating applied to an angular sector that corresponds to a friction area under contact pressure. This innovative approach helps to minimize friction and wear, ultimately prolonging the lifespan of the piston pin in high-stress environments.
