NIT Develops Monitoring System

MADRID — New Infrared Technologies (NIT) has developed DISCOVER IR SUITE, a system which allows brake disc manufacturers to monitor the high-speed laser metal deposition (HS LMS) process to guarantee quality assurance. 

This monitoring system will help ensure the accurate application of the high-speed laser metal deposition process, an affordable additive manufacturing technique utilizing lasers for repair and coating applications and a means of addressing brake-particulate emissions. 

Euro 7 regulates brake wear particle emissions for the first time as part of the Euro 7 EU vehicle emission standards. 

Arturo Baldasano, chief executive officer of NIT, explained “The innovative laser process effectively lowers the amount of harmful particulate matter in the air. Around 50 percent of particulate emissions from road traffic originate from the wear and tear of brakes, tires, clutches, and road surfaces, with brake dust accounting for almost half of this amount.

Brake discs coated with high-speed laser metal deposition release significantly less particulate matter compared to traditional brake discs.”

The only way to ensure the proper application of the coatings is through a monitoring process like the one developed by NIT, Baldasano added.

Volkswagen AG will be one of the first original-equipment manufacturers to install the DISCOVER IR SUITE on its production line.

Specific capabilities of the DISCOVER IR SUITE include:

Real time detection of:

• Dirty & defect surface identification.

• Powder flow rate.

• Powder line bended.

• Injectors blocked.

• Linear speed variations (feed rate).

• Nozzle misalignment.

• Powder leak. Able to quantify the leak size.

• Powder mass flow rate. Able to find a linear regression to quantify mass flow rate variations.

• Tungsten Carbide. Able to find a linear regression to quantify tungsten carbide proportions.
