"Identifying the Causes of Pitting Corrosion in 3D-Printed Stainless Steel"

Researchers at Lawrence Livermore National Laboratory have identified tiny particles called "slags" as the culprits behind pitting corrosion in 3D-printed stainless steel 316L in seawater. These slags, produced during the 3D printing process, remain at the metal's surface and initiate pitting corrosion, allowing chloride-rich water to penetrate the steel and cause damage. By understanding the mechanisms behind this corrosion, the study paves the way for developing improved materials and manufacturing techniques to create stainless steel components that are highly resistant to the corrosive forces of seawater, with implications extending beyond marine applications.

"Concerns Arise as Tesla Cybertrucks Show Signs of Rusting in the Rain"

Some Tesla Cybertruck owners are reporting early signs of rust and corrosion on the stainless steel panels of their EVs, with orange stains appearing after minimal exposure to rain. Debate rages on forums about the cause of the discoloration, with some attributing it to carbon dust or contaminants. The stainless steel construction has proven to be a headache for both Elon Musk and early adopters, as the Cybertruck manual confirms its susceptibility to corrosive substances. Tesla's cleaning recommendations suggest immediate cleaning after exposure to oil and acidic soiling, but some owners are frustrated by the additional cost of protecting the steel panels.

"Rust Concerns: Tesla Cybertrucks' Stainless Steel Issues"

Despite being made of stainless steel, Tesla Cybertrucks are showing early signs of rust and corrosion, with owners reporting orange stains on the exterior panels after minimal exposure to rain. Debate rages on the cause, with some attributing it to contaminants while others point to the steel's susceptibility to staining. The Cybertruck's stainless steel construction has proven to be a headache for both Tesla and early adopters, with the manual confirming its susceptibility to corrosive substances. Cleaning recommendations suggest immediate cleaning after exposure to certain elements, leading to frustration among owners who feel additional protection options are costly.

Unveiling the Secrets of Atomic-Level Corrosion

Researchers are using environmental transmission electron microscopy (TEM) to study the atomic-level reactions between water vapor and metal surfaces, specifically focusing on the formation of passivation layers that protect against corrosion. By introducing water vapor to clean aluminum samples, they observed the development of an amorphous layer underneath the aluminum hydroxide layer, indicating a transport mechanism that diffuses oxygen into the substrate. Understanding these atomic reactions could lead to better corrosion management techniques and clean-energy solutions, as well as significant economic benefits.

MBTA Station Safety Concerns Raised After Woman Struck by Falling Equipment

A corroded utility box that was part of a now-defunct biological agent detection system fell and hit a woman at the Harvard Square Red Line station in Cambridge, Massachusetts. The box's supporting brace, which weighed about 200 pounds, struck the woman, causing minor injuries. The MBTA has ordered inspections of support straps at all Red Line stations and the removal of 13 remaining utility boxes at Harvard, Porter, and Davis stations. The T called the incident an "isolated case" and vowed to have all inspections completed by the end of Tuesday.

Woman injured by falling equipment at Harvard MBTA station due to corrosion.

A woman was injured when a utility box fell on her at Harvard MBTA Station due to corrosion on the support straps. General Manager Phil Eng ordered immediate inspections of all stations to check the condition of the support straps. The MBTA believes the boxes are only on the Red Line and inspections are ongoing. Red Line service was not impacted by the incident. Two months ago, a falling ceiling tile nearly hit a woman at the same station, and the T later removed other tiles in that section of the station.

Honda recalls over half a million CR-Vs for rust and corrosion concerns.

Honda is recalling 563,700 older CR-Vs due to excessive corrosion that can cause the rear trailing arm to detach, posing a major safety risk. The recall is limited to certain states where road salt is used as a de-icer. Honda will offer to buy back affected vehicles if the rear frame is too corroded. Owners will be notified by mail to take their CR-V into a Honda dealership for inspection and repair. Honda has received 61 customer complaints related to the issue but is aware of no crashes or injuries.

Honda recalls over 560,000 CR-Vs in cold-weather states due to rust risk.

Honda is recalling 563,711 older-model CR-Vs in 22 cold-weather states and Washington, D.C., due to potential corrosion of the rear trailing arm caused by road salt, which could lead to detachment and loss of control of the vehicle. Honda will inspect and install a support brace or repair the rear frame, as necessary, for free, and may offer to repurchase the vehicle outright. The affected model year 2007-2011 CR-V vehicles were sold or registered in 22 states and D.C. Honda has received 61 complaints of road salt accumulating and causing frame corrosion.

Honda recalls over 560K CR-V SUVs in cold-weather states for rust risk.

Honda is recalling 563,000 CR-V SUVs sold or registered in cold weather states due to the risk of corrosion caused by road salt, which may cause the frame to detach the rear trailing arm. The recall covers 2007 through 2011 model year CR-V vehicles in 22 states and the District of Columbia. Honda may offer to repurchase recalled vehicles depending on the extent of any damage. No fatalities or injuries have been reported related to the recall.
