How specialized coatings can make mechanical parts harder for extreme industrial applications

Although bearings, gears, rollers, and other precision components are generally made of hardened steel or metal alloys, those used in high-load applications still can fail due to excessive wear, surface fatigue, pitting, galling, and corrosion. To address this problem, product engineers and component manufacturers often turn to specialized PVD (physical vapor deposition) coatings that can further harden the surface of these parts. Oerlikon Balzers provides solid solutions.

Stainless steel multiple-joint hinges

JW Winco now offers GN 7237 Stainless Steel Multiple-Joint Hinges with internal mounting brackets and a maximum opening angle of 180 deg. These multi-joint hinges are installed on the inside of flaps, hatches, or compartment doors to save space and ensure protection against vandalism. These hinges are generally used in pairs, meaning that one type L (left-hand) and one type R (right-hand) are used per opening. For higher loads, such as from large hatches, these can be supplemented with additional hinges of either type.

Conserve precious liquids with patented no-drip atomizing nozzles

EXAIR's new 1/8 NPT No Drip External Mix Atomizing Spray Nozzles mix liquid and air outside the nozzle and allow the air and liquid flows to be adjusted independently. The new, patented No Drip External Mix Atomizing Spray Nozzles work in the same way the company's standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. Post-spray drips waste precious resources such as expensive coatings, chemicals, or water.

Compact electronic slide bolt

Southco has expanded its line of electronic access control solutions with a compact electronic slide bolt that simplifies the upgrade from mechanical to electromechanical latching. The lightweight EM-05 5 Series Electronic Slide Bolt is suitable for light-load applications where space is limited, and the efficient gear motor-driven mechanism can be easily integrated with any control system. This unit features simple push-to-close functionality and offers an upgrade in energy efficiency compared with solenoid solutions, as no power is required to maintain the product's retracted or extended position. It offers simple installation and retrofits.

Spinning flare nuts eliminate loose fasteners in thin metal sheet applications

PEM SFN spinning flare nuts from Penn-Engineering become permanently captivated upon installation in thin metal sheets and, when paired with a self-clinching stud or other fixed externally threaded hardware, can eliminate all loose fasteners (including flange nuts) in attachment applications. These one-piece, flanged hex nuts additionally will spin freely in a sheet enabling quick attachment to mating hardware. Their use ultimately promotes savings in assembly time and costs.

How colorants affect plastic characteristics

If you're starting a custom plastic injection molding project, you'll want to select a material with the properties most suitable for the function of your parts. One aspect of polymer characteristics that doesn't always get the consideration it deserves is the addition of colorant. Believe it or not, there is a whole scientific body of knowledge about the ways in which adding color to plastic can affect the behavioral properties of the plastic. This short article by Denny Scher of ICO Mold takes a high-level look at some of the different, and surprising, ways colorants can have an effect on plastics.

Univ. Central Florida is selling experimental Martian dirt

Researchers publish recipe for Martian and asteriod simulant.

The University of Central Florida is selling Martian dirt, $20 a kilogram plus shipping.

This is not fake news. A team of UCF astrophysicists has developed a scientifically based, standardized method for creating Martian and asteroid soil simulants.

The team published its findings this month in the journal Icarus. The article is called "Mars global simulant MGS-1: A Rocknest-based open standard for basaltic martian regolith simulants."

"The simulant is useful for research as we look to go to Mars," said Physics Professor Dan Britt, a member of UCF's Planetary Sciences Group. "If we are going to go, we'll need food, water, and other essentials. As we are developing solutions, we need a way to test how these ideas will fare."

For example, scientists looking for ways to grow food on Mars need to test their techniques on soil that most closely resembles the stuff on Mars.

"You wouldn't want to discover that your method didn't work when we are actually there," Britt said. "What would you do then? It takes years to get there."

UCF's formula is based on the chemical signature of the soils on Mars collected by the Curiosity rover. Britt built two calibration targets that were part of Curiosity rover. Researchers currently use simulants that aren't standardized, so any experiment can't be compared to another in an apples-to-apples kind of way, Britt said.

As a geologist and a physicist, he knows his dirt. Like a recipe, the ingredients can be mixed in different ways to mimic soil from various objects, including asteroids and planets. And because the formula is based on scientific methods and is published for all to use, even those not ordering through UCF can create dirt that can be used for experiments, which reduces the uncertainty level.

Kevin Cannon, the paper's lead author and a post-doctoral researcher who works with Britt at UCF, says there are different types of soil on Mars and on asteroids. On Earth, for example, we have black sand, white sand, clay, and topsoil to name a few. On other worlds, you might find carbon-rich soils, clay-rich soils, and salt-rich soils, he added.

"With this technique, we can produce many variations," Cannon said. "Most of the minerals we need are found on Earth, although some are very difficult to obtain."

Cannon is in Montana to collect ingredients for a moon simulant this week. Moon and asteroid materials are rare and expensive on Earth since they arrived via meteorites in small amounts. That's why asteroid and moon simulants are also on the list of items that can be ordered. The UCF team can mimic most ingredients and will substitute for any potentially harmful materials. All simulants produced in the lab meet NASA's safety standards.

Britt and Cannon believe there is a market for the simulant. At $20 a kilogram, plus shipping, it may be easier to send UCF an order than to try and make it in labs across the nation.

The team already has about 30 pending orders, including one from Kennedy Space Center for half a ton.

"I expect we will see significant learning happening from access to this material," Britt said.

Cannon believes it will help accelerate the drive to explore our solar system, as demonstrated by investments already being made by Space X, Blue Origin, and other private companies.

For Cody Schultz, a mechanical engineering senior, getting to work on the experimental soil has been "very cool."

"For someone who has always loved space science, this is the ultimate cool," he said. "And the experience is fantastic in terms of the real world ... out-of-this-world experience."
