  • Alusil, Lokasil, Silitec, Diasil, Mercosil, ALBOND—These Sound
    Alusil, Lokasil, Silitec, DiASil, Mercosil, ALBOND—these sound like a foreign language, but they are all trade names or trademarks for what is generically known as hypereutectic aluminum, which is a new/old material for cylinder bore wear surfaces. Hypereutectic aluminum is both new and old. Its cousins, hypoeutectic and eutectic aluminum, have been used for pistons and connecting rods for a number of years. One of the earliest applications of hypereutectic aluminum was as the wear surface in an unlined cylinder in some Porsche engines in the 1960s. The 1971 Chevrolet Vega was the first true production automotive engine with a linerless hypereutectic aluminum cylinder bore as the wear surface. Despite the car’s reputation, the cylinder concept was ahead of its time. When properly finished, hypereutectic aluminum cylinder bores present a surface to the piston rings that is roughly equivalent to glass. The resulting engine has lower friction, excellent sealing, improved dimensional stability, improved heat dissipation, reduced weight, better recyclability, lower manufacturing cost and higher durability compared to the traditional aluminum block with cast iron cylinder liners. Aluminum Cylinder Evolution Since the first time gasoline burned and forced a piston down a cylinder, aluminum has been the metal of choice when light weight was the most critical requirement for an internal combustion engine. This is as true today as it was in 1902 when the Wright Brothers were unable to purchase a suitable commercial engine for their experimental airplane and instead built their own, casting the aluminum block. Automotive OEMs seized upon aluminum for the same reason and found manufacturing advantages, too, in that it is less costly to cast and easier to machine.

M. O. Kornfeld (Zhumal eksperimentalnoy i teoreti- cheskoy Fiziki (Journal of Experimental and Theoretical Physics), 1933, 3, (6), 563-566).—[In Russian.] Annealing of deformed polycrystalline aluminium in the region of “ pure recovery ” does not restore the original properties. The processes which take place during recovery lead to a highly stable con­ dition characterized by a yield-point higher than that of the original material due to the residual distortion of the lattice after recovery. Laue photo­ grams indicate that during recovery there is no noticeable shift in the boundaries between grains. It may therefore be concluded that any change in properties during recovery is determined mainly by processes taking place within the grain.—N.

Received: 15 November 2020; Accepted: 7 December 2020; Published: 9 December 2020 Abstract: The paper concerns modeling the microstructure of a hypereutectic aluminum-silicon alloy developed by the authors with the purpose of application for automobile cylinder liners showing high resistance to abrasive wear at least equal to that of cast-iron liners. With the use of the nanoindentation method, material properties of intermetallic phases and matrix in a hypereutectic Al-Si alloy containing Mn, Cu, Cr, Ni, V, Fe, and Mg as additives were examined. The scanning electron microscope equipped with an adapter for chemical composition microanalysis was used to determine the chemical composition of intermetallics and of the alloy matrix. Intermetallic phases, such as Al(Fe,Mn,M)Si, Al(Cr,V,M)Si, AlFeSi, AlFeNiM, AlCuNi, Al2Cu, and Mg2Si, including those supersaturated with various alloying elements (M), were identified based on results of X-ray diffraction (XRD) tests and microanalysis of chemical composition carried out with the use of X-ray energy dispersive spectroscopy (EDS).

  • Understanding Bore Scoring in Al-Si Cylinder Systems
    UNDERSTANDING BORE SCORING IN AL-SI CYLINDER SYSTEMS Charles Navarro LN Engineering LLC Copyright ©2019 LN Engineering LLC. Abstract The basic requirements for a cylinder lining are as follows: wear resistance for the liner, rings, and pistons, as well as resistance to galling and minimal oil consumption. In the beginning, internal combustion engines favored heavy, dense, thermally stable cast iron engine blocks for their durability in meeting these criteria. Besides being heavier than a modern all-aluminum engine, those made from cast iron provide poor cooling, limited performance, and are nowhere near as efficient or powerful as today’s engines designed to meet tightening emissions and fuel economy requirements.1 As aluminum has four times the thermal conductivity of cast iron or steel, it’s the logical choice to overcome these thermal performance limitations.2 However, Al-Si cylinder systems require special surface preparation and piston coatings, not to mention specific lubrication needs. Balancing these requirements has always been a challenge for engineers, especially when cost is the driving motivator for OEMs when utilizing liner-less cylinder technologies. Innovations built upon an all-aluminum engine designed to maximize efficiency and reduce emissions, coupled with hybrid technologies, will extend the life of the internal combustion engine as we transition to an all-electric future.

Part of that that has been coated with Nikasil® confusion. Alusil’s like Lokasil®, market involves small displacement should be aware of a few material Mercasil® and other high silica substrates engines of all types and configurations. properties and some of the confusion are not coatings at all but rather Past experience with these small bore surrounding them. It will not be the aluminum metal alloys. These alloys have engines has demonstrated a need to purpose of this article to cover many also been referred to as hypereutectic understand materials and coating in a manufacturing details but developing aluminum due to the percent of silica particles contained in the alloy.
