“…Building hard ceramic-type layers on the surface was also achieved using several techniques, like plasma electrolytic oxidation, Magoxide, Tagnite and keronite [25][26][27]. Silicon oxide layer -Tagnite process -as a conversion layer for further painting on magnesium alloys was developed by an electrochemical process [28] and a new anodic coating using Magnoxid-coat applied on die cast alloys [29][30] was found to improve the corrosion resistance of AZ31 alloy [5] .…”

Magnesium alloys are attractive alloys in industrial applications , where light weight and good strength structures are required. Magnesium alloys are versatile and include both cast and wrought alloys. However, they have a drawback as they are prone to corrosion especially in harsh environments. For this reason, surface treatment of magnesium alloys is of prime importance for improving their corrosion characteristics.In the present paper, a survey of the different methods for surface treatment of magnesium alloys is presented and discussed. This is followed by a review of the recent work on electroless Ni plating technique with zinc pre-treatment applied on several magnesium alloys and the effect of pretreatment and post heat treatment on the coat characteristics. The surface morphology, surface roughness, thickness of the layer, EDX analysis, adhesion, hardness and corrosion resistance are covered in this review.

“…The options for sealing the PEO coatings include the use of low viscosity sealers, sol-gel, paint, powder-coating and Ecoating, etc. [7,8]. The outer porous and rough layer of the PEO coating facilitates a good bonding/keying layer for sealers or top coat materials thus offering composite or duplex protection systems that are often superior to a single protection system taken individually.…”

This paper reviews various aspects of anodizing of magnesium alloys, such as the basics, processes, properties and applications. It systematically summarises the existing fundamental studies and technical developments of anodizing of magnesium alloys, and concludes that new anodizing processes based on electrolytic plasma anodizing that convert the surface of a magnesium alloy into a hard ceramic coating in an electrolytic bath using high energy electric discharges can offer improved wear and corrosion resistance. These new anodized coatings are often claimed to perform better than the traditional ones obtained through older anodizing processes, such as DOW17 or HAE. The new anodizing techniques are chromate free and hence environment friendly. It is expected that more cost‐effective, environment‐friendly and non‐toxic anodizing techniques will be developed and applied to magnesium alloy components in the future.
