Nitriding, Its Growth and Tribological Benefits for Surface Engineering

Day/Time/Room: Tuesday, October 15, 2019: 9:00 am 251A (COBO Center)

Speakers: Mark Hemsath , SVT VP of Sales & Marketing & Prof. Daniel H. Herring, The HERRING GROUP Inc.

Description: Nitriding is here to stay. Various nitriding methods, their history and processing options are compared in this review. A critical question is, "Why has the nitriding field grown so rapidly in recent years?" The answer is complex, but this paper considers the question by looking at two factors: tribological properties of nitrided layers, and advances in equipment and processes which have improved reliability, repeatability and flexibility.

Nitriding has a rich history spanning over 100 years. It is the nitrided surface itself that is largely responsible for increased interest. The surface engineering that is possible along with its predictable and relatively distortion-less results are huge factors in its growth.

The Future of the Integral Quench Furnace

Day/Time/Room: Tuesday, October 15, 2019: 9:40 am, 251C (COBO Center)

Speakers: Mr. Mark Hemsath, SVT VP Sales & Marketing, Prof. Daniel H. Herring, The HERRING GROUP, Inc., Mr. Tomasz Przygonski, SECO/WARWICK S.A.

Description: The heat treat industry is constantly advancing, and carburizing is no exception. Atmosphere gas and low-pressure vacuum carburizing are well known, well-established and distinct processes. However, rarely do these two technologies compete in the same commercial space. Gas carburizing in integral (sealed) oil quench furnaces is the workhorse of the industry while low-pressure carburizing produces the absolute best quality. Combining the best of both methods will result in a more competitive future!

Advanced Distortion Control for Heat Treated Components

Day/Time/Room: Tuesday, October 15, 2019 at 4:20 pm in Room 251B (COBO Center)

Speaker: Tom Hart, SVT Product Manager

Description: Material distortion is an undesired characteristic observed when a produced component requires a thermo-chemical heat treatment process followed by a rapid quench to obtain desired mechanical and metallurgical properties with uniform case depth and hardness profile. Due to the distortion taking place during this process, the manufacturer is faced with the costly choice of leaving excess material on a machined component before the heat treatment process, only to be removed after the heat treatment process by post heat treatment manufacturing methods.

This paper will discuss the unique method of distortion control for heat treated and quenched components by use of a 4-Dimensional High-Pressure Gas Quench (4D HPGQ) technique.

Triple Chamber Vacuum Furnace Systems - The Low Pressure Carburizing Workhorse

Day/Time/Room: Thursday, October 17, 2019 at 10:20 am in Room 251C (COBO Center)

Speaker: Don Marteeny, SVT Technical Director

Description: Multi-chamber vacuum furnace systems have become the system of choice for high throughput, highly precise low pressure carburizing (LPC) applications over the past two decades. Compared to traditional gas carburizing in continuous or batch integral quench atmosphere style furnaces, LPC run in modern vacuum furnaces reduces carburizing gas consumption while providing more consistent results when considering case depth, surface hardness, and core hardness. Multi-chamber furnaces provide this level of precision while also maintaining the high production level required in automotive or aerospace applications. To understand the potential benefits of these systems, two sample applications are presented using a triple chamber semi-continuous vacuum carburizing system. Both oil and gas quenching capabilities are considered. The results show the semi-continuous, triple chamber design is capable of similar, if not superior, results while providing increased productivity and uptime versus more traditional multi-furnace or continuous furnace systems.
