Surface Technology, Inc. began as a small family business during the recession in the early 1970s. Deeply rooted in history and innovation, the company has evolved into a world leader in composite electroless coatings.
In the early ‘70s near the end of the Vietnam War, the U.S. was mired in a downward economic spiral. As unemployment and inflation rose, so did the nation’s dependence on foreign oil. Emerging global competition in the metal industry triggered a steel crisis. The United States was in a recession. However, despite being surrounded […]
Frictional losses in gear boxes transform into heat, which makes them significant to gear box designers and will result in a fuel efficiency reduction for the vehicle involved. This effort is to measure and document the comparative friction losses in a gear mesh due to gear tooth surface condition and lubricant.
The most exhaustive experimental study quantifying gear tooth friction is by Yoshizaki , in which spur gears with various geometries were operated in a power re-circulating test rig and frictional losses were measured. Various lubricants and additives were also evaluated and tooth surface finishes (Rmax) ranging from 0.5 to 4 μm were considered. In Britton […]
Since 2009, BJ-Gear in Denmark has used collaborative robots from Universal Robots to automate its production of gear wheels. This new type of robots have ushered in substantial cost savings on machinery, optimized work flows, and created a more varied and rewarding work environment for employees that now welcome their new “colleagues.”
When asked how they envision a robot, most people either think of huge, unwieldy robots working in fenced off areas in large factories. Or, they think of futuristic cyberbots mimicking human behavior. But somewhere in between these two scenarios lies a new emerging reality — a new class of robots, dubbed “collaborative robots” due to […]
Ion-sulfurized lubricating gradient material (LGM) is a state-of-the-art technology conferring excellent anti-friction and wear-resistant characteristics on metallic parts, including gears, splines, and bearings. In this article, the engineering characteristics of LGM technology are introduced and exemplary applications are presented.
History Of Ion-Sulfurized Lubricating Gradient Material (LGM) Technology In modern industry, large fraction of machinery components, including gears, splines, and bearings, continually fall out of service because of wear and wear-related damages, along with which there is tremendous loss in raw materials, labor, and energy. Besides wear damages, friction consumes huge power share and decreases […]
There have been thousands of scholarly articles and how-to books written about heat treating and its related metallurgy. In past columns, I’ve opined that the success of any heat treat — captive or commercial — is directly associated with the competence of its maintenance supervisor and staff. Heat treat furnace maintenance is an acquired skill […]
The fast track from high school straight into a university is a popular decision across North America, but it’s not necessarily the right decision for everyone. For some, apprenticeships are a viable option.
Here in the United States, the word “apprenticeship” isn’t in the vernacular. Students often feel pressured to attend a four-year university straight out of high school instead of enrolling in a technical college or seeking employment in the manufacturing industry. Often, they’re not even familiar with those options. Although the university track is beneficial to […]

Calico Coatings was founded by Tracy Trotter, owner and former racer, so it makes sense that the company got its start in the motorsport industry. Would you tell me more about Calico’s history and how it grew to cover a wide range of industries? Calico Coatings has been in business for 18 years. It was […]
The History of Bending Fatigue, Part III
When creating a model simulation for gear and rolling element fatigue, a disciplined approach is the only way to get it right.
In rotating machinery, bending and contact fatigue life is a principle concern in design life. In all wrought and powder metal gearing and mechanical power transmission components, the interactions of forces, time at load, environmental concerns, geometry, and specific material selection — in addition to processing and treatments and inclusive residual stresses — make for […]
When facing the difficult decision of buying new or used machinery for your shop, take these suggestions into consideration.
For those of you who didn’t attend the recent American Gear Manufacturers Association (AGMA) annual meeting, you missed a great opportunity to network and hear about a number of issues that are and will affect the gear industry here and around the world. One of other major takeaways from the meeting was that many of […]
