MXRR SUPERFINISHED & DLC COATED COMPONENTS

MXRR offers different transmission and valve train components, processed with ISF and DLC coating. This process is the same used in Formula 1 and all extreme motorsport racing applications.

ISF process:

ISF also known as ISOTROPIC SUPERFINISHING is a patented process that allows to improve dramatically surface characteristics of mechanical components. The ISF removes all surface flaws derived from the machining and creates a non-directional (from Greek “ISOTROPIC”) low Ra surface. This translates into a processed surface without the asperities of the cutting tool.

The ISF process is carried out through polishing the components with special ceramic media, vibrating in equipment and calibrated lubrication with dedicated chemical compounds. The chemistry, which will not generate hydrogen embrittlement in high-strength steel parts, reacts with part surfaces to produce a soft conversion coating. As the parts rolls in the vibratory machine, the conversion coating is wiped from peaks by the weight of the non-abrasive, high-density ceramic media, exposing unreacted, underlying metal.

The peaks, being elevated, are wiped preferentially. Because the wiped coating was formed by reacting with the steel’s surface, coating removal results in a lowering of the peak. Recessed valleys between the peaks are untouched by the media, leaving the coating intact and the valleys untouched. The valley left, grant optimized lubrication.

MOTORSPORT EXTREME APPLICATIONS:

ISF processing is a “must” for all serious RACING applications. All motorsports teams around the world use this finishing process for all internal critical components of engines and transmissions.

The key competitive advantages are the INCREASED DURABILITY and DECREASED HEAT GENERATION.

DLC Coating Process:

MXRR offers an additional feature to its kits: all ISF processed components are further improved by adding DLC coating.

DLC also known as DIAMOND-LIKE-CARBON is a coating process, that deposits layers of are applied in plasma-assisted processes under vacuum with an accuracy in the μm range. This advanced coating technology contributes to enhanced performance and lifetime at the highest competitive level.

DLC has some of the valuable properties of diamond, including: high hardness, low friction, resistance to wear, chemical inertness and smoothness. In common terms, DLC is harder than natural diamond and slicker than "Teflon."

Diamond like Carbon Ta-C coated surface at the microscope shows as the structural elements are not crystallites but nodules of sp3-bonded carbon atoms.

DLC coated components have a surface up to 5 times harder than hardened steel. This provides highly stressed components with excellent protection against wear and thus increase their service lives. This hardness also makes parts more durable. DLC coating protects moving parts from abrasion maintaining smooth movement much longer than uncoated parts. Engines with DLC coated parts create more horsepower, and have longer lifetimes from mechanical parts that rotate, slide, and face other types of wear. For this reason, DLC is now standard practice on engine parts in all Formula 1, racing cars, motorcycles, and boats.

DLC coatings creates lower coefficients of friction. As friction is the enemy of almost all moving parts, lowering it creates nearly universal improvement, regardless of the application. Reduced friction also reduces the need for lubrication, which can be a critical factor in extreme racing applications.

Benefits:

- Friction losses reduced to a minimum

- Measurably improved power output and reliability

- Even under extreme conditions, DLC coated components live substantially longer

- Protection under lubrication starvation
