Corrosion wear of automotive parts


Recommended Posts

The phenomenon of loss of metal in the relative movement of parts is known as the wear of parts. The occurrence of wear will cause changes in the shape, size and surface properties of the parts, which will gradually reduce the working performance of the parts. Wear is sometimes beneficial, such as running-in. According to different friction principles, wear can be divided into abrasive wear, adhesive wear, fatigue wear and corrosion wear.

Corrosion wear:

The abrasion on the friction surface of parts caused by chemical or electrochemical reaction due to the action of external medium is called corrosive wear. Corrosion wear is divided into oxidation corrosion wear, chemical corrosion wear and fretting wear.

Chemical corrosion wear:

The abrasion caused by chemical reaction directly between the metal and the external medium is called chemical corrosive wear. When a part is working in corrosive gas or liquid environment, a chemical reaction film is formed on the surface of the component. The bonding strength between the reaction film and the base metal is usually low. When the parts move relative to each other, the chemical reaction film will fall off and cause the chemical corrosion and wear of the parts.

Electrochemical corrosion wear:

The abrasion caused by the electrochemical reaction of metal in the external medium is called electrochemical corrosion wear.

Fretting wear:

Fretting wear is called fretting wear, which is caused by alternating load or vibration on the surface of interference fit of parts.

Cavitation:

Cavitation erosion is a fatigue exfoliation phenomenon on the surface of a solid moving relative to a liquid due to the local high temperature caused by bubble rupture and high impact pressure.

      Advance Auto Parts introduced its No. 1 fan “Ed Vance,” representing the voice of an emerging segment of automobile enthusiasts: those learning to DIY and craving a partner on their journey.
      “In Ed Vance, Advance is providing an authentic, relatable, entertaining and category-exclusive bilingual voice to embody, represent and connect with these modern DIYers, living alongside them in their DIY journey,” Advance said in a news release. “And his name just happens to be like the brand … Ed Vance loves Advance.”
      Forty percent of motorists who maintain their own vehicles are between 16 and 34 years old, according to the company.
      “Ed’s name recognition will draw quick connection to the Advance brand and serve as a vehicle to communicate the great benefits Advance offers,” said Jason McDonell, executive vice president of merchandising, marketing and e-commerce at Advance Auto Parts. “Ed is able to tell short stories that become authentic and real and connect with a new era of car enthusiasts who have emerged during the pandemic. We leaned into this in developing Ed as ‘every person’s person,’ inspiring these motorists to try something new in caring for their automobile while accelerating our commitment to build personal connections with them.”
      “In a retail category largely seen as a ‘sea of sameness,’ Ed Vance further differentiates Advance as the need for vehicle maintenance increases parallel to the average age of automobiles in the United States reaching 12 years,” the company added in a press release.
      Ed and Advance’s “Do It Together” movement is threaded through all aspects of the new campaign, a connection-first approach guiding all marketing efforts and putting the customer journey front and center. Ed Vance is bilingual, introduced as “Eduardo Vance” to Hispanic audiences in all marketing. His persona first debuts on Instagram and Twitter (@EdVance4Advance), followed by 30-, 15- and six-second spots in both English and Spanish placed in media and on platforms relevant to the modern DIYer, including Roku, Spotify, Pandora, Twitch and more.
      Advance also recently debuted a new custom theme and sonic logo in two languages. “This is How We Advance” and “Avanza Con Advance” drive brand recognition and affinity for Advance while providing a memorable, hummable tune for DIYers.
      The arrival of Ed Vance comes as Advance celebrates its 90th “Advanceiversary” this summer by curating consumers’ most memorable moments on the road – the “Drive of Your Life” – for the chance to win a year’s worth of free Shell gasoline and possibly have their drive recreated.
