Cylinder Bore and Engine Block Coating – Apticote Ceramic 2000

Poeton Apticote Ceramic 2000 is the premier cylinder bore and cylinder liner coating technology, providing superior performance to that given by conventional Ni/Ceramic composite electroplates. Power is increased, streaking is eliminated, and piston skirt and ring wear is reduced.

Apticote Ceramic 2000 is slicker, harder, better bonded to the substrate, has more precise coverage and provides a superbly honed finish on engine blocks. By using a specialised coating composition the friction between the cylinder bore coating and the piston ring is reduced, and the lubricant retention on the surface is increased. Together, they provide for up to 3% increased engine power output, as in the dyno test below.

Key Features

  • High hardness
  • Low friction
  • Anti-streaking
  • Little on no wear
  • High precision
  • Coats any engine substrate
  • Easy honing
  • Compatible with any piston ring or piston
  • Superb bonding to the substrate

Hardness

microsection

560-600Hv, controlled by maintaining precise chemistry and ceramic content.

The ceramic filler is distributed evenly throughout the coating thickness, with the % content optimised for a combination of wear resistance and toughness.

Anti-streaking (scuffing, against the piston ring)

An end to streaking

With certain proprietary refinements, Apticote Ceramic 2000 virtually eliminates streaking on cylinder bores, cylinder liners and engine blocks; a problem that often occurs with conventional cylinder bore coatings. It is caused by pick-up of metal from the bore by the piston ring, which then scores the bore surface.

Apticote Ceramic 2000 discourages cross-transfer of metal, even with chrome plated piston rings, and minimises any possibility of streaking.

An end to this

Coating Thickness

The coating thickness after honing is 50 to 75µ, with ultra high precision on the final bore dimension.

Honing the coating

The coating is precision diamond honed by skilled machinists, closely controlling the finish and size.

Substrates

Apticote Ceramic 2000 can be applied to cast iron, steel or aluminium alloys, whether liners, cylinders or blocks.

Applications of the Apticote Ceramic 2000 Cylinder Bore Coating

1) For the OEM market worldwide

The Poeton customer base extends throughout Europe and across the Atlantic to the USA, providing a high quality, rapid turnround cylinder bore coating service for the Original Equipment Manufacturers (OEMs). Our customers come from the automotive, aerospace and defence sectors, and we meet rigorous quality specifications for volume, repeat business.

Cylinder Liners

Poeton can coat all types of cylinder liner, using a multi-station plating unit. Flow rate, current density and the electrolyte chemistry are precisely controlled, ensuring consistent and reproducible results.

Cylinder liners

Rotary Housing – cast aluminium alloy

Rotary Housings

Poeton coat hundreds of cast aluminium alloy rotary housings (including for use in UAVs), employing a custom designed bespoke tooling , ensuring the highest quality control. As with all our production, 100% bonding to the substrate is confirmed by regular destructive testing (saw cut, fracture) of representative test rings.

Engine Blocks and Four-Bores

Cast engine blocks, including in-line, V6 and V8 configurations, and motorcycle four-bores are coated using dedicated manifolds. Bespoke tooling is required, being most cost-effective when there are multiple units to coat.

Four-bore

2) Motorcycle Barrels, including a service for the weekend racing enthusiast

Poeton coat all types of two-stroke and four-stroke motorcycle barrels, be they for motor-cross, karting, snowmobiles, off-road or GP racing.

As well as the OEM market, a proportion of our work on motorcycle barrels is for the lone racing enthusiast, someone who wants his engine refurbished in a hurry. For this we offer our unique ‘Cylinder Express’ service, a 4-day turnaround that returns your cylinder to pristine condition.

  • Turn out to remove streaking or gouges
  • Check and correct the flatness of the gasket faces
  • Weld repair and turn out any major bore damage
  • Weld repair any damage from detonation, broken bridges or ports, cracked O-ring groves, and worn out exhaust pipe flanges
  • Narrow-down over-ported exhaust ports
  • Coat the bore with Apticote Ceramic 2000 and precision hone
