The improvement of adhes.on s.rength and durability of plated contacts.is.required for cell manufacturers.to gain confidence for large-s.ale manufacturing. To overcome weak adhes.on at the metal/s. interface, new approaches.were developed. Thes. involve the formation of las.r-ablated anchor points. or grooves.in the extreme cas. of overlapping anchor points. in the heavily doped s.licon s.rface. When plated, thes. features.greatly s.rengthen the mechanical adhes.on s.rength of the metal. A s.ylus.bas.d adhes.on tes.er was.developed s.ecifically for evaluating the effectivenes. of plated contacts.to s.ooth s.licon s.rfaces. The us. of s.ch a tes.er was.als. extended in this.work to textured and roughened s.rfaces.to allow evaluation of different metal contacting approaches. The adhes.on s.rengths.for various.metal contacting s.hemes.were evaluated, including s.reenprinted s.lver contacts. nickel/copper （Ni/Cu） light- induced plated （LIP） contacts.for las.r-doped s.lective emitter （LDs.） ceils. buried-contact s.lar cells.（BCs.s., and Ni/Cu LIP contacts.formed with las.r-ablated anchoring points.in s.lective emitter （LAAs.） cells. The latter has.s.perior adhes.on s.rength. The s.andard ＂peel tes.＂ of the indus.ry was.compared to the s.ylus.bas.d adhes.on tes.ing, with the latter s.own value for tes.ing metal contacts.on s.ooth s.rfaces.but with caution needed for us. with textured or roughened s.rfaces.

We propos. a new s.ructure for artificial joints.with a joint caps.le which is.des.gned to overcome the drawback of current pros.hes.s.that omit many functions.of the lubricant and the joint caps.le. The new s.ructure is.compos.d of three components. lubricant, artificial joint and artificial joint caps.le. The lubricant s.aled in the caps.le can not only reduce the wear of the artificial joint but als. prevents.the wear particles.leaking into the body. s. unexpected reactions.between the wear particles.and body can be avoided completely. A three-dimens.onal （3-D） finite element analys.s.（FEA） model was.created for a bionic knee joint with caps.le. The s.res.es.and their dis.ribution in the artificial caps.le were s.mulated with different thicknes., loadings. and flexion angles. The res.lts.s.ow that the maximum s.res. occurs.in the area between the artificial joint and the caps.le. The effects.of caps.le thicknes. and the angles.of flexion on s.res. are dis.us.ed in detail.

The biodegradability and biocompatibility of porous.Mg-2z.（mas. fraction, %） s.affolds.coated with nano hydroxyapatite（HAP） were inves.igated. The nano HAP coating on Mg-2z. s.affolds.was.prepared by the puls. electrodepos.tion method. The as.depos.ted s.affolds.were then pos.-treated with alkaline s.lution to improve the biodegradation behavior and biocompatibility for implant applications. The micros.ructure and compos.tion of s.affold and nano HAP coating, as.well as.their degradation and cytotoxicity behavior in s.mulated body fluid（s.F） were inves.igated. The pos.-treated coating is.compos.d of needle-like HAP with the diameter les. than 100 nm developed almos. perpendicularly to the s.bs.rate, which exhibits.a s.milar compos.tion to natural bone. It is.found that the products.of immers.on in s.F are identified to be HAP,（Ca,Mg）3（PO4）2 and Mg（OH）2. The bioactivity, biocompatibility and cell viabilities.for the as.coated and pos.-treated s.affold extracts.are higher than thos. for the uncoated s.affold. MG63 cells.are found to adhere and proliferate on the s.rface of the as.coated and pos.-treated s.affolds. making it a promis.ng choice for medical application. The res.lts.s.ow that the puls. electrodepos.tion of nano HAP coating and alkaline treatment is.a us.ful approach to improve the biodegradability and bioactivity of porous.Mg-z. s.affolds.
