Low-wear brake coatings for a regulated emissions future

LACS is a candidate pathway to durable brake disc coatings that may support reduced particulate emissions and Euro 7 compliance — subject to validation.

REGULATORY TIMING

Euro 7 sets the timeline for heavy-duty brake wear

LFT is targeting Laser-Assisted Cold Spray (LACS) as a scalable coating technology for the next generation of commercial-vehicle brake discs.

Euro 7 applies to new M2, M3, N2 and N3 vehicle types from 29 May 2028, with heavy-duty brake-particle limits expected to apply following the prescribed regulatory review from 1 January 2030. LFT is therefore positioning LACS for OEM development, dynamometer validation and industrial scale-up ahead of this emerging market requirement.

KEY DATES

29 MAY 2028

Euro 7 applies to new M2, M3, N2 and N3 vehicle types.

1 JAN 2030

Heavy-duty brake-particle limits expected to apply, following the prescribed regulatory review.

Dates reflect the Euro 7 regulation as published; heavy-duty brake-particle limits remain subject to the prescribed regulatory review.

Brake wear is becoming regulated

Brake wear is becoming an emissions issue

Euro 7 sets a defined compliance timeline

Heavy-duty commercial vehicles face demanding braking cycles

Coatings must balance durability, cost and scalability

Manufacturers need practical compliance pathways

WHY EXISTING APPROACHES FALL SHORT

Some coating processes are expensive

Thermal processes can create distortion or material compromise

Scalability may be difficult

Heavy-duty cycles increase wear and performance demands

LACS deposits dense, hard, low-wear coatings while avoiding melting-based thermal effects. Its ability to work with hard material systems makes it a candidate pathway for brake applications where durability, cost and scalability matter — subject to validation.

What success looks like

Reduced brake wear

Lower particulate emissions

Improved coating durability

A more affordable candidate compliance pathway

Strong relevance for commercial vehicle applications

Material systems relevant to this application

Candidate coating systems for low-wear, Euro 7-relevant brake discs — reinforced stainless systems with buffer layers where required.

430L stainless + 10 wt% TiC

Hard ceramic-reinforced top layer (~150 µm) targeting low brake wear and Euro 7 particulate limits; a 316L buffer (~100 µm) is considered where needed.

LACS RELEVANCE

LACS has not yet deposited this exact stack, but its low thermal impact may reduce dilution into the cast-iron disc — potentially reducing or removing the buffer layer.

Proposed application-specific system, subject to validation

Carbide-reinforced stainless (e.g. SS + 10 wt% WC)

The durable, hard, wear-resistant coating class brake discs require.
